2024 Bluebird Nesting Begins Early

young bluebird
The vibrant male Western Bluebird atop the nest box is alert for any competitors or predator. One of his chicks watches from inside.

Bluebird nesting season got an early start with a fully formed grass nest inside a nest box near the hospital. The nest has a cup in the center where the female will lay the eggs. Nest monitors began checking boxes this month, so they can note nest progress and the dates when: the first egg is laid, additional eggs are added (usually 4-6 total), incubation begins, eggs hatch, and nestlings fledge.

Monitors dedicate their time from March to August, checking each nest box once per week. They send the season’s information to Bluebird Chair Matt Lee, who collates the data and compares the current season tally with preceding years. The monitors carry on the important work Elsie Elzroth began in 1979, and the Western Bluebird population has grown to a self-sustaining population since then. Thanks to all the volunteers.

Birding Field Trips

Second Saturday field trip participants scour the trees in Willamette Park for winter birds.

Second Saturday (half-day) field trips to local birding areas are led by Duncan Evered and Caryn Stoess from September through June.

Birding & Resources

gray-crowned rosy finch
Due to its remote and rocky alpine habitat, the Gray-crowned Rosy Finch is a special find!

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.

Education Workshops

Use your senses to explore nature poster
The Kalapuyans are a Native American ethnic group. Their traditional homelands were in the Willamette, Elk Creek, and Calapooya Creek watersheds of Western Oregon (Link). Recent workshops explored local Kalapuya history and ecology with stories, games, and uses of native plants and animals. It also included an exploration into fire management practices and restoration following fire.
Education Program
The Education Team has connected people to nature for the past 30 years. Events are often held at Hesthavn, our small Nature Center on Oak Creek Road. Due to the Coronavirus pandemic, our plans for the coming year are limited, so check here for updates.

Bluebird Trail

Western Bluebird
Western Bluebird population declines galvanized Elsie Elzroth 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.
