Monthly Speaker

Red Crossbill
Red Crossbills are usually found in noisy flocks near the tops of trees.

How Birds and Other Wild Animals Survive Unpredictable Environmental Conditions
Digital Video Presentation – October 15 at 7:00 pm

OSU researcher Jamie Cornelius studies Red Crossbills, a finch with a highly adapted bill specific for foraging on conifer cones. Jamie will explain some of the fascinating adaptations that this little bird uses to cope with one of the most stressful and dangerous conditions that animals face in their environments – that of unpredictable food and harsh winters. To enjoy more photos about Jamie’s presentation OR to listen to recorded video presentations from previous speakers, click Monthly Speakers.
We are unable to meet in person for our monthly presentations due to Covid-19. Instead our presentations are digitally recorded and can be watched at the scheduled time or can be viewed as a recording. The public is invited to this free seminar, however, attendance is limited to 100 people. To register or for more information, contact

Where the Birds Are

Corvallis smoky sky
On September 8, smoke from the Cascade fires was blown into Corvallis, creating eerie skies, falling ash, and hazardous breathing.

When the unusual east winds blew ash and smoke from four huge Cascade fires into the Willamette Valley, people were warned about the hazards of being outside. Since other animals are also affected by the smoke, how do they cope? The National Audubon Society has information on their website about the effects on birds.

Look for migrating waterfowl, including Cackling Geese, to begin showing up in the mid-Willamette Valley by mid-September. Wintering flocks of Northern Shovelers, American Wigeon, Northern Pintail, Green-winged Teal, Ring-necked Ducks, Lesser Scaup, and more should show up a bit later.

Birding Field Trips

Due to the pandemic, our half-day and multi-day trips are canceled until further notice. Field Trips

Summer Birding with the Audubon Society of Corvallis!
If you’ve been missing our field trips (due to COVID-19 group activity restrictions) we can offer the next best thing, a virtual video field trip to Pigeon Butte at Finley Wildlife Refuge. Come see the birds and other creatures we saw as well as 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 to learn about birds.

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.

Connect with Nature While at Home

Use your senses to explore nature poster

Due to the Coronavirus pandemic, the ASC Education Team’s plans for the coming months are on hold. But our KEY message for this year is to encourage everyone to Connect with Nature. Enjoy nature wherever you find it, from a bird singing in the tree outside your window to a beautiful bloom in your yard or neighborhood. Click below to see our Connect with Nature poster. There are lots of ideas about how to use all your senses to explore, learn, and connect to nature around your home.

Education/Outreach    Poster 

Audubon for Kids! A plethora of nature activities from across Audubon’s educators, including the classroom curriculum Audubon Adventures, plus related DIY activities and content from Audubon’s editors. These activities can be done at home or in a yard or park. Allow kids to find their own connections to nature.


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! The Nature Center will be staffed with volunteers and open to the public for special events. Events will be featured here, on the kiosk at Hesthavn, and in the Gazette-Times Calendar.
