Monthly Speaker

Nitrogen fixation in plant roots

Steve Perakis
Red Alder Legacies Deplete Calcium in Oregon Forests: What the Shell is Going on?
Video Presentation – March 18, 7 pm

Steve’s research focuses on the biologic, geologic, and chemical cycling of life-sustaining elements (carbon, nitrogen, phosphorus, etc.) in ecosystems – especially forests. Natural and human factors, such as fire, disturbance, climate change, affect nutrient availability and soil fertility, and Steve studies how they influence plant growth, ecosystem development, and carbon storage.
   Due to Covid-19, our usual in-person meetings are digitally recorded and can be watched at the scheduled time or can be viewed as a recording. Non-ASC members are invited to this free seminar, however, attendance is limited to the first 100 people to join the meeting. For more information, contact   
   To view the video presentation from previous month – see Monthly Speakers.

Where the Birds Are

Harlequin Ducks
Harlequin Ducks are commonly seen along the South Jetty in Newport.

   Tree Swallows were sighted at Willamette Park and Philomath Sewage Ponds in early March. Turkey Vultures and Rufous Hummingbirds are beginning to appear in the Willamette Valley. Canada Geese are staking out nesting sites. A Winter Wren was seen in the McDonald-Dunn Forest (Oak Creek watershed) from February 28 – March 6.
   It’s easy to socially distance on a day trip to Newport. March 12 was exceptional weather-wise, and the herring started spawning the day before. Check: south jetty of Yaquina Bay – more than 30 Harlequin Ducks, Surf Scoters, and White-winged Scoter, Common Loons, Osprey, Bald Eagles, Lesser Scaup, Buffleheads,, and more. Hatfield MSC Estuary Trail – Brant, Whimbrels, and Marbled Godwits. Yaquina Head Interpretive Center and Lighthouse – Peregrine Falcons, thousands of Common Murres.
   Check sightings on eBird around Corvallis and the American Birding Association Birding News.

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.

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, 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 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.
