Monthly Speakers

American Kestrel
A stationary American Kestrel is a rare sight! This pose highlights the amazing flexibility of its tail, which facilitates quick maneuvers during flight and access for a good spring cleaning.

December 19 is Members Photo Night! Photographers share their best nature photos and stories from local and international areas. Bring no more than 20 of your favorites for a presentation of 5 minutes so everyone can showcase their adventures.

Look Who’s Here

Snow Bunting
During breeding in the Arctic, Snow Buntings are white and black, but add rusty patches to blend in on bare ground and croplands in winter.

Posted to Mid-Willamette Valley Birds:
– The mountain regions of Linn/Marion counties are part of our mid-Willamette Valley watershed, and are areas of concern for our local Audubon chapters. Look for grebes, loons, scoters, and mergansers on mountain lakes on their way to the coast for the winter. Better odds (and scenery) than at local sewage ponds. (Joel Geier, Oct. 28)

– Snow Buntings are confirmed near the summit of Marys Peak. Black-tipped white primaries, buffy face with brown cheek spot behind eye, broken chestnut collar, grey-brown coverts, yellow-orange beak. Check for Clark’s Nutcrackers, Townsend’s Solitaires, Canada Jays, stray Cassin’s Finches, Gray-crowned Rosy-Finches, Crossbills, and Evening Grosbeaks. (Joel Geier, (Oct. 26) Day-use fee or federal Senior Pass required.

Birding Field Trips

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

Opportunities abound in our region to view, photograph, draw, or paint birds. Ten half-day trips to local areas are offered monthly. Although geared to novice birders, these trips are also open to new residents, visitors, and anyone else who enjoys nature. Multi-day trips to regional areas are scheduled during peak birding times.

Field Trips

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.

Teaching about Birds

Dark-eyed Junco
Dark-eyed Juncos are winter residents of the Willamette Valley. The stout beak, long tail, and white outer tail feathers visible in flight are characteristic of this sparrow.

Do you want to learn more about local birds in the Willamette Valley? Two separate sessions of the Beginning Birding Workshop will be held February 1 and 29. The goal is a fun introduction to bird identification, field guides, binocular use, bird-watching culture, backyard birding, and more. There will be a classroom session and practice time outside looking for birds.

Education/Outreach – class


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 of a Nature Center that is located in northwest Corvallis.

The Nature Center started life as a barn, and now it offers a museum with taxidermied birds, 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. The trails and garden are open from dawn to dusk everyday. Admission is free! In addition, the Nature Center will be staffed with volunteers and open to the public on Dec. 14 and Jan, 11, 2019 and Jan 25, 2020.
