Welcome to the Audubon Society of Corvallis!

Where birds and wildlife count

ASC is headquartered in Corvallis, Oregon and welcomes members and visitors from the mid-Willamette Valley and beyond. We host speakers, lead half-day birding walks

to local areas, guide multi-day field trips to regional birding areas, present education programs to all ages, and support conservation of birds, other native wildlife, and natural habitats.

**Special Note: Avian Flu 2022**

Avian flu (AvFlu) does not affect all birds the same way. Both raptors and domestic poultry are highly susceptible to the current strain, but wild songbirds are not and they do not transmit the disease easily. The Centers for Disease Control notes that transmission of AvFLu from birds to humans is very rare.
     The Cornell Lab of Ornithology, working with the USDA APHIS National Wildlife Disease Program, has compiled a summary of research

on this year’s spread of AvFLu. Because the disease is a very low risk for wild songbirds, they do not recommend taking down those bird feeders. However, people who raise poultry or waterfowl should separate domestic bird food from wild bird feeders. Nest box monitors should wear disposable gloves or wash their hands well. Please click here to see the whole article.
     Bird feeders and bird baths must be cleaned regularly in any season but especially to prevent

 the spread of AvFLu. Remove droppings and dirt from the outside of the feeders, wash them in soap and water or a 10% bleach solution, and rinse well. Another option is to wipe down the ports and outside of the feeders with rubbing alcohol. For bird baths, dump out existing water, spray with a hose, then use a brush to remove algae and other debris. Rinse again and fill. For nesting boxes, remove all debris once the season has ended.

Keeping an eye on your birds is also important – lethargy or other abnormal behavior may be an indication to clean feeders or take them down for a period of time. Hummingbird feeders also need frequent cleaning, and should be washed only with soap and water or a dilute vinegar solution and rinsed well. Bald eagle deaths from AvFlu – NYT

Monthly Presentation

“Marbled Murrelets: The Enigma of the Pacific”
by Dr. Jonathon Valente
May 19, 2022 – ZOOM Presentation at 7:00 pm

Marbled Murrelet
Marbled Murrelet on nest in old-growth forest

Marbled Murrelets are stocky seabirds that make big changes as the breeding season nears. Their crisp, black and white plumage turns  brown, and they fly inland to nest in old-growth forests. Logging and climate change are current hazards to population viability and the species is listed as Threatened in Washington, Oregon, and California. Dr. Valente is currently working as part of the Oregon Marbled Murrelet Project to better understand factors limiting the distribution of this endangered seabird.

Monthly meetings begin at 7:00 pm and are open to the general public, although space is limited. Contact for information about accessing the program.

World Migratory Bird Celebration
May 21 – 28 


ASC is partnering with the Willamette Valley National Wildlife Refuge Complex (WV) to celebrate World Migratory Bird Week. The spring migration is a natural wonder as an estimated one billion birds use the Pacific Flyway to travel from their southern wintering grounds to their northern breeding grounds. The journey is difficult, and birds must refuel where there is abundant food. National Wildlife Refuges are ideal places to see birds as they pass though. Events will be held at all three WV sites: Ankeny, Baskett Slough, and Finley. Besides naturalist-led hikes at all three WV sites, there are crafts, games, activities, and a bilingual preschool program. Visit the website for event times, descriptions, and maps.

Birding Field Trips

Field trip participants focus on a bird despite the wonderful view.

Second Saturday (half-day) field trips to local birding areas have resumed and are led by Duncan Evered and Caryn Stoess. Please see Field Trips for registration and more information. Multi-day trips are canceled until further notice.

Summer Birding with ASC!
Hesitant to join our half-day field trips? The next best thing is a virtual field trip (via video) to Pigeon Butte at Finley Wildlife Refuge. See the birds and other species and meet the birders. This video is being shared with Aves Compartidas (Shared Birds) program in the Willamette Valley which connects students in the U.S. and Mexico as they learn about birds. Link

Birding & Resources

Our region is a prime place to find, watch, draw, and photograph many species of birds. Half-day field trips to local areas and multi-day trips to regional birding areas are led by ASC guides. New birders and anyone else interested are invited to participate. Find more information about ASC Birding at the links below.

Directions to Hesthavn


Homer Campbell boardwalk trail
Visitors check out the Homer Campbell Boardwalk Trail at Finley NWR, which was constructed by ASC and partners.

ASC participates in grassroot conservation by providing information about pending actions on national and state environmental laws. Locally, ASC has joined partners to conserve habitats, provide access on trails, and restore native plants. Conservation of Western Bluebirds and Streaked Horned Larks are other major initiatives for ASC.

Conservation/Protection        Priorities

Bluebird Trail

Western Bluebird
Western Bluebird population declines galvanized Elsie Eltzroth to make a difference.

The ASC Bluebird Trail committee was created to promote the conservation of the Western Bluebird (Sialia mexicana) and other native cavity-nesters through field work, scientific studies, and education. A series of bluebird boxes have been placed in ideal habitat for the birds. Volunteers monitor the nesting success throughout the breeding season, and results are reported to several organizations.

Hesthavn Nature Center

Hesthavn welcome sign
Hesthavn is a hidden jewel located in northwest Corvallis.

Due to Covid, the Nature Center is closed until further notice, but our trails are open from dawn to dusk everyday.
The Nature Center started life as a barn, and now it offers a museum with taxidermied birds, Bluebird Trail and other exhibits, and a classroom. The Center is staffed for special events – check the calendar on this page. The property includes trails, bird feeders, and a native plant garden. Meadow restoration is one step in the long-term goal of restoring all habitats. Admission is free! The Nature Center will be staffed and open to the public for special events. See this space, the kiosk at Hesthavn, and the Gazette-Times Calendar.
