Monthly Speaker

Green jay
Like most jays, Green Jays are very vocal all year except for the breeding season.

In order to maintain Social Distancing, the May 21 Chapter Meeting will be a Zoom video presentation at 7:00 pm. Fred Ramsey will enlighten us with photos and stories about his trip to Oaxaca in 2000. Nearly half of all species in Mexico are found in this area, including nearly 750 species of birds.

Look Who’s Here

Flocks of hundreds of Greater White-fronted Geese continue to be seen and heard heading north/northwest [April 25]. They’re most easily recognized by their “laughing” calls and their straggly formations which tend to be in broader V’s than Canada or Cackling Geese, often also with the arms of the V’s forking in to multiple smaller, messy-looking V’s like a hand-drawn genealogy chart. Apparently…these broader formations are the most energy-efficient way for them to fly.

There has been some speculation that this year’s migration through the Willamette Valley is larger than in past years…however when Dave Budeau was manager at E.E. Wilson Wildlife Area in the 1990s and early 2000s, he’d regularly note thousands of these geese passing over, with peak passage during April 24-27.  ~ Joel Geier, Mid-Valley Birding

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. Seven multi-day trips to regional areas are scheduled during peak birding times from March through August.

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, and that is more relevant than ever. Take advantage of the unexpected break in your routine to find peace and inspiration in our natural world. 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. Be aware and enjoy.

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.

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.
