Monthly Speakers

Jamie Cornelius
“Wandering the Earth with Nomadic Finches: Lessons learned about facultative migrations”
November 18, 2021
*ZOOM Presentation – 7:00 PM

Red Crossbill

Birds are the harbingers of spring as migrants move north and begin singing. These north-south waves of billions of birds are familiar to most of us but there are many birds for whom north-south is not always the way. Nomadic and irruptive species live lives of flexibility – responding to less predictable fluctuations in food that can vary in timing or location. Dr. Cornelius will share some of what she’s learned about life as a wanderer from red crossbills, pine siskins, goldfinches, zebra finches, and more. 

Please check this space for current updates on whether the presentation will be in-person or on Zoom. The meeting will begin at 7:30 PM and be followed by the ASC Business Meeting when needed. Meetings are open to the general public but are space limited. Contact for information about accessing the program.  Monthly Speakers

New Ray’s Trail Guide

Check out new guide for this 0.2 mile trail at Hesthavn. Learn about how ASC volunteers are restoring and conserving this former horse pasture. Even this small preserve contains different habitats, and many native animals and plants can be found here. Also, wildlife cover boards offer a refuge from heat, cold, rain, or predators for small animals. There are three cover boards along the trail in slightly different habitats. See how different animals use the refuges throughout the year.

Birding Field Trips

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

Summer Birding with ASC!
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.

Kids! Find the Birds in Corvallis

Black-capped chickadee
Black-capped Chickadees are found in any area that has trees or woody shrubs. They only stay long enough at seed feeders to grab one and go. (All About Birds)

ASC Education volunteers offered Bird Tails and Trails in four local Corvallis parks during the Natural Areas Celebration Week in May 2021. Activity sheets from those events are still available for you to download. Discover the most common species in that habitat and track down the food, water, shelter, and plants that the park’s bird population needs. Park worksheets are:
  Sunset download       MLK download

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 and open to the public for special events. See this space, the kiosk at Hesthavn, and the Gazette-Times Calendar.
