At 31 years old I had a slumber party with my 3 year old niece and my 2 year old nephew at my sister's house. We ate homemade pad thai (my favorite!) for dinner, followed by popcorn and ice cream while watching "Elf." Possibly one of the most fun nights I've had in a while. We woke up to fresh coffee cake (for the vegans) and crepes (for the non-vegans). My niece told her mom "Hey, you're supposed to be gone" when she saw my sister in the kitchen. When it came time for me to leave my niece and nephew were so disappointed that I wasn't staying with them another night. I'm sure my brother-in-law thought it was silly, but I'm quite thankful for the adventures.

Mountains
I went into the mountains today, to find trees for decorating the houses of my parents and each of my sisters. Five dogs and four kids later I feel full of joy. The dogs were good (mine even listened the whole time!) and the kids full of laughter. We talked about trees and rocks and lichen and moss. We often talk about birds too, but I'm certain the altitude and the ruckus kept any birds in the area at bay. The lack of snow did not dampen spirits, though sledding is certainly more fun than playing in the dirt. Perhaps the snows will come soon enough for a family outing before Winter Term starts again. Being an auntie is one of the greatest joys in my life. Sharing my love for birds and nature the icing on the cake.

Snowy Owl Adventure
What a wonderful birding adventure I embarked upon yesterday. People have been seeing a snowy owl in Albany and a mountain plover near Corvallis, for several days now. I am generally not a "seeker" of birds. I see what I see wherever I am and am happy with that. But...I have always wanted to see a snowy. Over the summer I decided that I would go to their "normal" Oregon winter hangouts. Then, it turns out it is an irruption year for snowies, with larger numbers of them coming further south than in a typical year. Albany is about four hours from Ashland, but I didn't care. My post Fall Term of Graduate School celebration would be going to find the Albany Snowy Owl. A friend from the cohort came along and we met my birding compatriot in Eugene. After some delicious baked goods at Sweet Life we headed west/northwest on hwy 99W, toward Corvallis. The mountain plover was off of a road near one of my favorite wildlife refuges, Finley Wildlife Refuge, in a large field. Once we selected the right field it took mere minutes to spot the plover, but it was not alone. A winter plumed black-bellied plover was hanging out with it. Not my first black-bellied, but a wonderful surprise either way! We then headed to find the snowy in Albany. It was amazing how easy the snowy was to spot, in the large green field it was hanging out in. Particularly compared to finding the mountain plover (brown in a brown field). I know that snowies are big, but nothing I've read, no photos that I've seen, prepared me for how big and how wonderful snowies are in person. The bird was clearly a female, based on the amount of black barring on its chest. We watched him for quite a while, moving slowly away from us in short bouts of gliding. After a bit we drove to a road that took us closer to the snowy. The highlight of watching the snowy was having it fly toward us, land, look to the north, glide up, gracefully drop to the ground and bounce back up into the air with a large rodent in its talons. Of course, watching the owl swallow the rodent whole was even more delightful! Pizza Research Institute pizza after birding rounded out the delightful adventure. Happy birding.

Extended weekend
This weekend is a four day weekend. While not having a schedule to constrain my life is wonderful, I have many projects due in the coming week. Thus, my weekend is not nearly as full of relaxation as I'd like. My winter break will be similarly structured with gift making, thesis proposal writing and PhD professor seeking on the agenda. Hopefully, there will be enough snow for a little snowshoeing too.

Snow Day
My dog loves the snow so yesterday I hiked up the mountain behind my house, hoping to find snow for her. We found a couple of inches at the higher elevations, making for a wonderful way to start the day. On the hike back down the mountain an adult red-tailed hawk and a raven circled over head for a short portion of the hike. In that moment I felt so happy, and so lucky to be alive. To live where I live. To be so completely happy to "just" watch birds. A lovely morning indeed!

Thesis Project
Okay, all you birders out there, I have a favor to ask of you. My thesis project has changed quite a bit from my original idea. In its current form the project is "The Effects of Birder Use of Playback on Bewick's Wrens and Song Sparrow." In putting together the methods for this section I have come across some question that I cannot answer myself. How do birders use playback? What time of day are most birders out birding? Where do most birders acquire the songs they use for playback? What kind of equipment do most birders use when they use playback? If you, or anyone you know, uses playback, or if you have suggestions or thoughts on these questions, please let me know. Any assistance you can provide will be much appreciated! Cheers!

Fall Term
Man, oh man, this term has been hectic! Between class, work, my thesis proposal and planning meetings for the fall outdoor education program that my cohort will be putting on next fall I seem to have little time to stop and think. Or blog for that matter. I've never been in Ashland for more than a day trip, so this fall has been interesting. The irrigation ditch is now dry. The neighborhood bears and foxes hang out closer to my house (both leaving scat behind and the foxes talk a lot!). During the peak of fall migration there were hundreds of swallows performing their aerial acrobatics over Ashland. Turkey vultures also gathered over Ashland before heading south. In one day I counted over 40, and that was after I finally gave up and just stared up at their thermally soaring silhouettes. Now the white-crowned and golden-crowned sparrows hang out in the bushes around town and the winter flocks of black-capped chickadees, ruby-crowned kinglets and golden-crowned kinglets have come down from the higher elevations. There are occasional flocks of bushtits and every now and then I hear a brown creeper. Moments of reflection on the cycles of life, circadian rhythms and changes both in my life, self and the nature around me are wonderful distractions from the bustle that my life has become.

Reflections on summer as autumn begins
This has been one of those summers that didn't turn out at all as I had planned. I didn't hike as much, or bird as much, as I wanted to. Or camp as much for that matter. I did make it to Yellowstone, a center of geothermal activity that I have wanted to see for the better part of 30 years. What an amazing place. I didn't have nearly long enough there and at some point I'd like to go back and backpack/hike the back country. While in Yellowstone I saw the largest elk I have ever seen, it literally seemed the size of a small buffalo, being stalked by a lone black wolf. I've longed to see a wolf in the wild since they first started the reintroduction of wolves in Yellowstone so I was delighted beyond belief at the sighting. There were also sandhill cranes in some of the grasslands of Yellowstone. Sandhill cranes are one of those birds that I never see enough of, likely in part because I don't live where the cranes live. On the way home from Yellowstone there was a stop at Malheur National Wildlife Refuge, yet another place I've always wanted to visit. This one is much closer to home than Yellowstone and after having been there I'm not sure why it has taken me so long to go. There were white-faced ibis there, a bird I've always wanted to see but never make it to the Klamath NWR at the right time of year to find. There were hundreds of ibis foraging in the shallow waters of the refuge! While at MNWR I also saw a loggerhead shrike (I've missed them since my time in Boardman), common nighthawk, bank swallows, black-necked stilts and a myriad of other birds that I don't commonly see. I've always adored yellow-headed blackbirds. Before MNWR I'd only ever seen a handful, if that. At the refuge they were everywhere, it was amazing! I've also never been somewhere when swallows are staging for the flight south. They certainly seem to use MNWR as a staging sight. Along one stretch of road, perched on the powerlines, there were close to 1,000 swallows (mostly bank but also violet-greens, cliff and barn swallows). Just amazing. When I got back from the trip I was finally unemployed, in between terms and had nowhere specific to be, nothing specific to do. Needless to say I have actually been relaxing for the last few weeks. I hike or walk often but as I have my dog with me normally I don't see nearly as many birds as I'd like to see. I've been camping a few times. Finished unpacking my boxes. I also put together a rough draft for my thesis proposal (okay, a VERY rough draft), which is due at the end of fall term. If I'm approved I'll be studying the effects of recreation on grassland birds. I'm not sure where or if I'll be looking at specific birds or not, these things will unravel themselves in time. Ultimately, the downtime has been very good for me. The last year has been busy and often emotional so...it is nice to just sit and process. Here's to the changing of the seasons and to many more blogs about birds (well, I hope anyway!).

Northern spotted owls, barred owls and forest management
In the local paper they recently mentioned that a plan has been created that involves removing barred owls from all northern spotted owl habitat via lethal measures. The reasoning behind this planned seemed to be mostly presumption and conjecture. Wanting to know more about the impact barred owls are having on northern spotted owls and the reasoning behind the plan I wrote about this issue for my Environmental Issues class presentation. What I discovered is that there isn't much scientific evidence that barred owls are to blame for the northern spotted owl population declines. Loss of habitat leading up to the northern spotted owl's listing under the Endangered Species Act is the main culprit but there are all manner of other confounding factors. The paper follows.
Northern Spotted Owls vs. Barred Owls: Interspecific Complications, the Endangered Species Act and Management Implications
The Situation
One of the greatest conservation and land use debates, in the Pacific Northwest, in the last two decades has been the listing of the northern spotted owl (Strix occidentals caurina) as Threatened under the Endangered Species Act (ESA) of 1973. The 1990 listing of the northern spotted owl lead to a 90% decrease in logging on 24 million acres of federal lands, managed by both the US Department of Agriculture Forest Service (USFS) and the Bureau of Land Management (BLM), over the last twenty years. This decrease in timber harvest lead to an economic collapse in many parts of the Pacific Northwest, particularly Oregon, as private mills and timber companies had to close their doors.
The northern spotted owl is a small brown owl with white mottling or spots that hide it well in the dense canopies of late-successional forests, also favored by timber companies, that are found in their geographic range. Various studies conducted in the 1980s indicate that habitat is a limiting factor in the survivability of northern spotted owls and as such must be conserved in order to ensure the survival of the species. The 1990s-era closure of much of the late-successional forests of the Pacific Northwest ensured the habitat would be available for the expansion of northern spotted owl populations. Despite the availability of habitat northern spotted owl numbers continue to decrease by three times the rate of decrease noted at the time of listing.
Concurrent with the decrease in northern spotted owl numbers scientists have noted an increase in the numbers of barred owls found in the Pacific Northwest. The barred owl (Strix varia varia) is a cousin of the northern spotted owl and originally found east of the Great Plains, from Maine to Florida. There are many theories as to how and why the barred owl arrived in the west. These theories include an increase in the number of small stands of trees in the Great Plains, increasing summer temperatures creating a more ideal temperature range in the boreal forests of Canada, increased fire suppression efforts and changing forest dynamics due to timber harvests. Regardless of the reason that barred owl range expanded west their ability to live in diverse habitats, eat a diversity of prey species, their more aggressive nature and 20% larger size allows them to outcompete northern spotted owls for habitat and food.
In 2007 resource managers began proposing barred owl elimination programs in an effort to combat the interspecific competition happening between barred and northern spotted owls. These programs call for the shooting of hundreds of barred owls in the Pacific Northwest and have been met with significant opposition from the scientific community and the general public. Many scientists agree that controlled barred owl elimination studies could provide helpful in determining the overall impact that barred owls are having on northern spotted owl populations but a large scale culling would be time consuming, could be expensive and would have to be regularly maintained in order to have lasting impacts.
Background Information
· In 1973 the ESA was passed. This allowed for the designation of species as either endangered or threatened, defining endangered as a species “in danger of extinction throughout all or a significant portion of its range” and threatened species as “a species likely to become endangered.” Under Section 4 of the ESA allows for subspecies, such as the northern spotted owl, to be listed as a threatened or endangered “species,” allow the same level of protection as is given a species and requires both a Recovery Plan and Critical Habitat Designation to be created for all listed species (Stanford Environmental Law Society, 2001).
· The Interagency Scientific Committee to Address the Conservation of the Northern Spotted Owl (ISC) found that northern spotted owls select habitat with a relatively closed canopy, a variety of vegetation layers with a diversity of canopy species dominated by large overstory trees, large trees with broken tops or cavities, the presence of large snags, large logs and woody debris on the forest floor and openings within and beneath the canopy. These habitat attributes are typically found in mature late-successional forest but can be found in younger mid-successional forests that retain either several individual large trees or small stands of large trees from the original late-successional stand (Thomas, Forsman, Lint, et al, 1990).
· At the time of listing, all the studies of Spotted Owl habitat use concluded that owls select old forests or younger forests that have retained characteristics of old forests. Studies published since the ESA listing decision provide additional support that habitat selection is significantly nonrandom (Noon and Blakesley, 2006).
· Barred owls were first sighted west of the Rocky Mountains in 1912, in southern Alberta, Canada (Levy, 2004).
· Northern spotted owl populations have continued to decline since the 1990s, despite being listed as Threatened under the Endangered Species Act and habitat conservation efforts. Scientists are uncertain as to why this decline isn’t reversing.
· Weather and climate can impact northern spotted owl reproduction, recruitment, annual survival and population growth rates. Increasing drought conditions and increased precipitation during nesting season will likely negatively affect northern spotted owl populations (Glenn, Anthony and Forsman, 2010).
· Interspecific hybridization between barred owls and northern owls, creating offspring called “sparred owls” occurs in some instances. These instances often occur in areas that barred owls have recently invaded and are therefore less common than northern spotted owls or in areas where northern spotted owls have become rare and barred owls are common.
· There are many examples of multiple owl species coexisting in the same habitat. These species are typically from different genera and are successful in coexisting due to interspecific differences in behavior (Gutierrez, et al.; 2006).
· Owls exhibit reverse sexual dimorphism; females are larger than males.
· Barred owls from the Strix varia sartorii subspecies and spotted owls from the Strix occidentalis lucida subspecies have a sympatric relationship in Mexico. S. v. sartorii is the largest subspecies of barred owl and S. o. lucida is the smallest subspecies of spotted owl. The difference in mass of these species is a factor of two, a ratio that facilitates coexistence. The northern spotted owl S. o. caurina and the northern-most subspecies of barred owl S. v. varia differ in mass by a factor of 1.8, a number that statistically seems to support competition between species (Gutierrez, et al.; 2006).
· Genetic bottlenecks have been detected in many populations of northern spotted owls. These bottlenecks create situations of inbreeding depression that could decrease the rate of reproduction and an increase in population decline. A decline in genetic variability combined with competition with and exclusion by barred owls, climate change and habitat loss may be confounding factors in the efforts to save the northern spotted owl from extinction (Funk, et al.; 2009).
· From 1994-2003, northern spotted owl populations declined by 7.5% per year throughout northern ranges and 2% per year throughout their southern ranges (Rapp; 2008).
· Timber harvest on federal lands has occurred at only about 54% of the amount allowed under the Northwest Forest Plan (Rapp; 2008).
· Fire suppression in areas where fires are a normal part of the ecosystem, for example in the Klamath-Siskiyou bioregion, can put northern spotted owls at greater risk of habitat loss because of the build up of fuels.
· About 59% of spotted owl habitat occurs on federal lands (Rapp; 2008).
· According to the 10-year review of the Northwest Forest Plan the wood products industry employment has dropped by 70% since the implementation of the Northwest Forest Plan, due in part to the lower than expected number of boardfeet of timber harvested.
· In areas where barred owl numbers are the highest and time since invasion has been the longest spotted owl numbers have decreased by 20-25% (Wiens, Anthony and Forsman; 2011).
· The high cost of putting together a timber sale due to the required surveys (spotted owl and various other wildlife surveys) and potential lawsuits has contributed greatly to the greater reduction in logging that required by the Northwest Forest Plan and northern spotted owl Habitat Conservation Plan.
· A recovery plan for the northern spotted owl was drafted in 1992 but was never signed because of the creation of the Northwest Forest Plan in 1994. In 2008 the US Fish and Wildlife Service issued a recovery plan for the northern spotted owl. After pressure from scientists and a court challenge of the recovery plan the Service filed for a voluntary remand of the plan, filing a Revised Recovery Plan in 2010. The final Revised Recovery Plan was released June 30, 2011.
· The Revised Recovery Plan will likely increase timber harvest in spotted owl habitat as the USFWS recommends “ecological forestry” management that allows for thinning in late-successional ecosystems that northern spotted owls are found in (USFWS; 2011).

There are a variety of actions being proposed by various groups, agencies or organizations. Many timber companies are claiming that barred owls have been to blame for the spotted owl decline all along and are advocating for increased timber harvests in mature or late-successional forests in the northern spotted owl’s geographic range. Some forest managers have suggested eliminating barred owls from spotted owl habitats, while scientists prefer the idea of experimental removal, as not enough is understood about interspecific interactions between barred owls and spotted owls. Still other scientists, conservationists and members of the general public advocate for no action under the premise that barred owls are a native species and that it is natural for shifts in species to occur.
Author’s Position
The majority of information present explores northern spotted owls and habitat use or influences of habitat. Barred owl interactions with northern spotted owl populations have become a popular topic of study in the last five years. Based on the available science more research needs to be done in terms of how barred owls are affecting northern spotted owl populations and what other factors are confounding recovery efforts. One research area should be climate/weather as climate change or shift occurs researchers, conservationists and land managers could see further decreases in northern spotted owl numbers. Another area of study that will be important is the specifics of interspecies interactions that barred owls and northern spotted owls experience. Small scale experimental control of barred owl populations in northern spotted owl habitat will provide researchers with the information they need to assess the threat from barred owls to spotted owl recovery. The actions that should not be taken are increasing timber harvesting (aside from some thinning of areas that are in need of thinning to promote forest health), large scale removal of barred owls from spotted owl habitat and the “no action” action. Drastic measures are almost always ill-advised, particularly in manners of wildlife or land management.

Graduate School
Graduate School has "officially" started, though it started in June for me in actuality. The two classes I am currently taking are "Curriculum, Instruction and Assessment" through the College of Education and "Environmental Issues" through the Biology Department. The education class is going to be a bit rough but that is because state standards are appalling and a tad hard for me to wrap my brain around. I am willing to acknowledge that standards will not some how equalize the playing field intellectually but rather create problems for youth at both ends of the learning spectrum. I have to come up with an environmental issue to write about for the environmental issues class. The scads of possible topics make this a rough decision but I really do need to make it by 1400 hours tomorrow. I've started talking/thinking thesis too. My interests are so varied and my mind is not always a focused mind so this process is a little daunting right now. Anyway, I'll post on here as often as I can. Currently I'm trying to unpack, work in the community garden and attend graduate school so I will not likely be posting again for a few weeks. Cheers to you all. Enjoy the sunshine and birds (particularly as the little ones are fledging and oh so funny to watch!)!

Yurok and California condor paper.
Traditional Ecological Knowledge and the California condor: Bringing the Condor Home to Yurok Tribal Homelands
Teresa Wicks
SSPC 507
June 16, 2011
In the time since European contact, Indigenous peoples of North America have witnessed the decline or extinction of many species of plants and animals that they depend on for both physical and spiritual sustenance. In the early 1900s, as destruction of “untamed” nature continued to expand west, unregulated some Euro-Americans began advocating for the preservation, conservation or restoration of species, resources and ecosystems. Despite positive efforts on behalf of the ecosystem, these early naturalists continued the dehumanization of First Nations peoples by leaving them out of the conservation conversation and by perpetuating the idea that areas uninfluenced by Euro-Americans are uninfluenced by humans in general.
In an effort alleviate environmental problems, resource managers turned to western science, once again ignoring the very peoples that originated from this land. In “Indian Givers” Jack Weatherford makes the astute observation that First Nations peoples were scientists before there were scientists. They have an intricate understanding of the land around them and how all things are connected and through this connection affected each other. There have been many reintroduction and restoration projects that have used western science, excluding traditional ecological knowledge held by the people that lived here since time immemorial. The Ecological Society of America, in the Traditional Ecological Knowledge (TEK) section of their journal, defines TEK as “[a]daptive ecological knowledge developed through an intimate reciprocal relationship between a group of people and a particular place over time” (Ecological Society of America, 2010). The Alaska Native Science Commission lists these bullets in their definition of TEK:
• It is practical common sense based on teachings and experiences passed on from generation to generation.
• It is knowing the country. It covers knowledge of the environment - snow, ice, weather, resources - and the relationships between things.
• It is holistic. It cannot be compartmentalized and cannot be separated from the people who hold it. It is rooted in the spiritual health, culture and language of the people. It is a way of life.
• Traditional knowledge is an authority system. It sets out the rules governing the use of resources - respect, an obligation to share. It is dynamic, cumulative and stable. It is truth.
• Traditional knowledge is a way of life -wisdom is using traditional knowledge in good ways. It is using the heart and the head together. It comes from the spirit in order to survive.
• It gives credibility to the people.
There is a growing awareness of and interest in the value of TEK among western scientists. Unfortunately, this interest often only extends to cultural heritage, ignoring the inherent knowledge that TEK offers. Additionally, “the current regulations and practices in many regimes still do not provide effective formal mechanisms for the integration of TEK into active management” (Menzies and Butler, 2006). TEK is a highly detailed, specific set of knowledge about a specific place, meaning it is difficult to extrapolate the knowledge from on place to another. In the view of many western scientists this decreases the effectiveness or value of TEK. In reality, this specificity emphasizes the importance of gathering TEK from as many areas, about as many management practices and about as many species as possible.
In the case of the California condor TEK will play a vital role not only in understanding the traditional range of the condor but in creating a long lasting reintroduction plan that takes into account the condors historical range and habitat and the cultural importance of the condor.
California condors, Gymnogyps californianus, are the largest terrestrial birds in North America, with a wingspan of 9.5 feet, occasionally reaching 10-12 feet, and weigh between 18 and 23 pounds. Condors are scavengers using their keen eyesight to live off of carrion, which they will fly up to 140 miles to gorge themselves upon. Contrary to popular myth condors cannot pick up and carry off small children or livestock, in fact they “have never been known to kill a live animal” and are ill equipped to do so as they lack talons and the ripping/tearing predatorial beaks of other birds of prey (Foster, 2011).
California condors are found in open scrubland or wooded mountain ecosystems. They require cliff-side caves or crevices or hollow, broken top redwoods. Condors have low reproductive potential, laying only one egg every other year. Chicks generally remain with their parents into the second year after hatching. Similar to other large North American birds California condors do not reach sexual maturity until they reach six years of age, though they are often not successful until they reach eight years of age, and are monogamous, mating for life (Yurok Tribe 2010).
Geographically California condors once ranged across most of the North American continent. About 11,000 years ago, when the late Pleistocene megafaunal extinctions occurred the condor lost major sources of food and their range dwindled to the west coast, from British Columbia to Baja, California. By the mid-1900’s condors were found only in southern California (Yurok Tribe, 2010; Foster, 2011). In terms of numbers by 1977 there were only 45 wild birds, slipping to only nine wild birds by 1985. On April 19, 1987 the last wild California condors were captured and placed in captivity. At that point there were 27 living California condors left in the world, all of them in captivity (Foster, 2011). With such an extensive history on the North American continent, and with plenty of ideal condor habitat remaining the precipitous drop in condor numbers was puzzling, that is until human interactions were taken into account.
California condors are highly revered by many First Nations tribes in the Pacific Northwest and California. Condors are often considered world purifiers because of their natural role cleaning up death and decomposition. “Traditional ecological knowledge expressed through original languages, stories, place-names, material artifacts and dance all highlight the significance of condors in the ancient indigenous cultural context of the Northwest” (Oregon Zoo, 2005). An archeological dig at Five Mile Rapids, near The Dalles, OR unearthed 10,000 year-old remains of at least 22 adult condors. There is evidence that the feathers from these birds had been intentionally stripped, likely for ceremonial purposes (Wilbur, 2010). Condor feathers played an important part in the Jump Dance and White Deer Skin Dance world renewal ceremonies held at the end of summer by the Yuroks in northern California. The Wiyot, also of northern California, considered condor feathers an important part of their doctoring regalia. Tribes throughout the San Francisco Bay area of California made whistles out of condor wing bones, wore condor capes and ritually buried condors (Foster, 2011; Walter, 2009; Wilbur, 2010). While there is a plethora of evidence that many tribes killed condors for their plumage or raised young condors for eventual sacrifice condor populations appear to have been stable until the arrival of European settlers in the mid-1800’s (Wilbur, 2010).
There is evidence that as early as the mid-1700’s Euro-Americans killed condors for “science” or museum collections but it wasn’t until western tribes were virtually eradicated or removed from their traditional lands that condor numbers began to decline. Private collectors and museums from around the world wanted both adult and young California condor skins and eggs for their displays, encouraging unregulated hunting of condors. Ranchers and farmers mistakenly believed that condors would kill their livestock or carry off their children, leading to the further shooting of condors. Ranchers also laced livestock carcasses with strychnine in order to kill coyotes, wolves and condors. Possibly even more damaging than the direct human effects were the indirect Euro-American effects (Wilbur, 2010).
These effects include the thinning of condor eggshells, causing them to break under the weight of incubating parents, from DDT and DDE (a pervasive chemical derived from the breakdown of DDT) used in pesticides after World War II. Another indirect effect is lead poisoning caused by the consumption of lead shot left in carcasses or gut piles by hunters in condor territory (Walter, 2009; Grube, 2009). Thus, much like the First Nation tribes that revere them, the California condor is a victim of both intentional destruction and thoughtless actions on the part of Euro-Americans.
In 1987, several agencies, including U.S. Forest Service, San Diego Wild Animal Park, Los Angeles Zoo, Oregon Zoo, California Department of Fish and Game, the Peregrine Fund, Ventana Wildlife Society, the Center for Scientific Investigation and Graduate Studies in Ensenada, La Secretaria de Medio Ambiente y Recursos Naturales (SEMARNAP), National Park Service at Pinnacles National Monument, Santa Barbara Zoo, the Chapultepec Zoo in Mexico City, gathered together to attempt to right the wrongs inflicted on the California condor, in the form of a condor recovery program. In 1992 the first 11 captive bred condors were released from their “training facility.” Since 1992, the number of captive and wild condors has increased to 322 birds, about 172 are living in the wild.
The interesting thing about the current condor recovery program is that it is only attempting to reintroduce California condors to Arizona, near the Grand Canyon, in a few locations in southern California and in Baja California, Mexico. None of these programs seem to include TEK or the interest of tribes that live in former condor habitat. This changed in 2008 when the U.S. Fish and Wildlife Service granted the Yurok $200,000 to determine the feasibility of reintroducing California condors in northern California.
The journey to bring the condor back to northern California began sometime around 2005 when the Yurok began discussing the creation of a wildlife preserve on tribal lands. In a 2009 interview, Tiana Williams, tribal member and staff member with the Yurok Tribe’s wildlife program, is quoted as saying “It’s written in the Yurok constitution, and it’s always been one of our goals, to have restoration of Yurok ancestral territory — the landscape, the animals — to what it was pre-contact with Europeans” (Walters, 2009). The California condor was chosen as one of the top three species tribal elders would like to see reintroduced, coming in third to salmon and sturgeon. Salmon and sturgeon already have programs in place, thus the California condor became the flagship species for the Yurok’s fledgling wildlife program. An interesting aspect of the condor being the first species reintroduce to Yurok homelands is that the Yurok view condors as purifiers, cleansing the world (Grube, 2009).
About 20 years before the tribe began this endeavor, as they began reviving traditional ceremonies, a Pecwan elder sang a condor song. This was the first time that tribal members had heard the song, leaving many members wondering what happened to the condor. Yurok tribal member Bob McConnell says “We as Yurok are looking to restore our culture, and to restore our culture we need to have a healthy ecosystem. And to have a healthy ecosystem you’ve got to have all the participants, and the condor certainly was one. He’s one of the big missing pieces” (Walters 2009).
Today, the Yurok use a combination of TEK and western science in planning for the return of the condor. TEK, and a deep cultural appreciation for condors, inspired the Yurok Tribe to dream of seeing condors flying over their homelands once more. Tribal wildlife managers use intimate, local knowledge of condor natural history to establish survey areas. In these areas they live trap turkey vultures, carrion eating cousins of the condor, using large mesh and PVC enclosures and carrion as bait. Once trapped the turkey vultures are given a thorough examination and their blood is drawn and tested for lead, DDE and DDT. Northern ravens are also being drawn into the research mix. They eat a diet more varied than the condors but similarly do not migrate, unlike turkey vultures, which winter south of the border (Grube, 2009).
As it stands today the Yurok have confirmed that DDT and DDE levels will not pose a barrier for California condors. Unfortunately lead, from lead shot, still poses a problem for condor reintroduction. Lead shot has been banned in many, if not all, areas where condors are found but hunters still use it and condors are still poisoned by it. Diligent condor recovery team members capture poisoned condors and take them into captivity for chelation (the removal of lead from their blood). The removal of lead shot from condor territory seems like a small hurdle but in reality it has been one of the greatest challenges for condor recovery (Peregrine Fund, 2008; Zoological Society of San Diego, 2011).
The ambitious efforts of the Yurok Tribe have inspired other tribes in California and the Pacific Northwest to dream of seeing California condors in their skies once again. The Confederated Tribes of the Yakama Nation have partnered with the Oregon Zoo to sponsor the zoo’s condor breeding program and The Confederated Tribes of Siletz Indians have spoken publicly about bringing condors back to Oregon (Oregon Zoo, 2005). The Yurok Tribe’s condor reintroduction program showcases the value of TEK to natural resources conservation, preservation, restoration and management. This condor program also pairs western science and TEK in a blend that could, and should, inspire leaders from tribes, non-profits, government agencies and other non-governmental organizations. In keeping with TEK, honoring their traditional connection to condors and maintaining and managing the place of humans in the natural world the Yurok Tribe are regaining some of the balance that the tribe and the natural world they live in lost with the coming of Euro-Americans. By combining western scientific methods and tools with TEK, the Yurok have created a complete reintroduction system for the California condor, giving hope to tribes throughout traditional condor range, that one day they will get to once again watch California condors drifting on thermals, searching for carrion and cleansing, purifying and restoring balance to the world.

Life has been busy!
So it has been quite some time since I last blogged. I have been birding, hiking, running the community garden, camping, trying to get my move to Ashland, OR organized and educating myself. In June I took a week long class about Native American Cultures taught by David West, of Potawatomi descent, and David West, a Wasco man from the Warm Springs Reservation. This class was extraordinarily insightful and I feel my perspectives and perceptions expanding. For this class I wrote a paper about California Condors and the Yurok efforts to restore the condor to their lands, with a history of the condor and their importance to tribes from the Columbia River to southern California. It is interesting to me that the condor and the tribes' fates have been fairly linked considering condors were so sacred to so many tribes. It is also interesting to me that despite my appetite for bird information I had no idea that California condors once flew over the majority of the continent. Or that even after white Euro-Americans arrived in the Americas that condors flew over the western edge of the continent from British Columbia to Baja California, Mexico. Amazing things we can learn when we allow the people the originated on this continent to speak their knowledge. Their truth. When we allow them to be part of the conversation, history, plan, etc., rather than treating them as outsiders or eliminating them by dehumanizing them. My mind reels as I write this. Blogging will possibly continue being sparse for a bit as I will be living in two places, attending graduate classes and driving across the country and back in a salute to the end of summer and the beginning of a new chapter of my life. Enjoy your summer!

Meadowlark Prairie Take Two
Sadly, not my picture my digital camera has been dead and gone for six plus months. Click here to find out more.
The new sighting was a flock of about 14 dunlins! They are superbly cute little sandpipers. I had no idea what they were at first, besides being a species of sandpiper, and had left my bird book in the car (overconfidence). Thankfully, their black bellies makes their markings pretty easy to remember! Other distinctive features of the dunlin include moderately long legs, a longish bill that curves down a bit (describe by All About Birds as being droopy), a rather short neck and a reddish back. According to All About Birds Life History page about dunlins, dunlins that nest along northern Alaska migrate west along Siberia and Asia to Japan and China. The International Union for Conservation of Nature and Natural Resources (IUCN) lists them as a species of Least Concern with their populations abundant but possibly declining. It occurs to me that maybe I have seen them before but because I only sta

Warblers!
Black-throated gray warbler borrowed from this website.
I woke up early last Thursday (April 21, 2011) and went bird watching in Fish Hatchery Park before work. I have been anxiously awaiting the return of the black-throated gray warbler for most of the winter. These little black and white birds are stunning and they have a pretty fun song. All told I saw four species of warbler; black-throated grey, yellow, orange-crowned and yellow-rumped. I also saw a Hutton's vireo. These little guys resemble ruby-crowned kinglets both in behavior and appearance and they can be found here year-round. Birds that can't be found here year-round that I am hoping will return soon are western wood pewees and Pacific-slope flycatchers (various other flycatchers too). Finally, I haven't encountered any yellow-breasted chat yet this year. I think they returned in May last year so I am hoping they will be gracing my life soon.

Ethno-ornithology: Double-crested cormorants
Adult double-crested cormorant in non-breeding plumage. Photo information available here.
My good friend Flicker Boi has written several blogs about using lethal measures to reduce or remove populations of non-native birds from areas where they are in direct breeding, foraging or nesting competition with closely related species of threatened or endangered birds. Lethal methods of population control seems to be the most common form of control, likely because we are more familiar with this form of control. Eminant Domain says we should conquer, control and subdue nature (and the people that live close to it). Hunters relish the chance to kill coyotes, cougars, wolves and other "pests." This leads me to my current train of thought. Double-crested cormorants (Phalacrocorax auritus) are the most common species of North American cormorant (and darn cute). Their numbers are on the incline and thus they are the focus of blame for declines in sports fishing and for "devastating fish farms" (All About Birds, 2011). In 2003, true to our "lethal control" nature, a management plan was proposed by the United States Fish and Wildlife Service to use depredation to decrease the North American population of double-crested cormorants by <160,000 birds (U.S. Fish and Wildlife Service, 2003). Before I go any further let me just say that I'm not sure why managers are not allowed to use lethal measure to control populations of FERAL horses, cats, etc (not that I am advocating for the slaughter of these animals...though I do advocate RESPONSIBLE management) but it is encouraged in regards to NATIVE species (cougars, coyotes, cormorants, wolves, etc). My assumption is that horses and cats are charismatic/domestic species so we feel a stronger connection to them. Or maybe it's just Eminant Domain in another form.
"In 1998, the Service issued a depredation order (USFWS 1998b; 50 CFR 21.47 ) authorizing commercial freshwater aquaculture producers in 13 States (Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Minnesota, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, and Texas) to take DCCOs, without a Federal permit, when found committing or about to commit depredations to aquaculture stocks. The depredation order states that DCCOs may be taken by shooting only during daylight hours, and only when necessary to protect freshwater commercial aquaculture and State-operated hatchery stocks and that such actions must be carried out in conjunction with a non-lethal harassment program certified by APHIS/WS officials."
"(1) a member of the Kiowa Tribe of the State of Oklahoma felt that since waterbirds are sacred, they should be given to Tribal people for use in their native ceremonies; (2) the White Mountain Apache Tribe of Arizona recommended that we use a hunting season to manage DCCOs; and (3) a Conservation Officer from the Wampanoag Tribe of Gay Head (of southeastern Massachusetts) said that they have experienced some trouble with DCCOs roosting on the Tribal Shellfish Aquaculture Program’s spawning/rearing cages and recommended limited hunting."
