Vaux's swifts
Vaux’s Swifts

Posted to Mid-Willamette Valley Birds:
– On 1st Street just south of Madison, a small group gathered to watch the evening show of Vaux’s Swifts going into the chimney to roost for the night. Based on last evening’s count of 2000+, we estimated that there were 5000+ tonight. It took over 1/2 hour for all the birds to enter the chimney and at almost full dark there were still a few in the air. This is the most I have seen in many years. (Mary Garrard, Oct. 1)
– A kettle of over 20 Turkey Vultures circling over the woods on Powder House Road. I don’t think I have even had Vulture on any October list! (Oct. 6)
–  Sharp-tailed Sandpiper at Ankeny NWR, Eagle Marsh, far right near corner, part hidden in grass. (Oct. 7)

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

The ASC Education Team has provided outreach and activities for classes and events for more than 30 years. How does your wingspan compare to the world’s largest birds? How does flight differ between birds and bats? Custom programs can be arranged for groups. ASC also led the creation of Winter Wildlife Field Day which has grown in the past 5 years, attracting over 700 visitors, 16 partner organizations, and 137 volunteers in 2019 alone!

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!
