Bluebird Nesting Data 2023: Fewer nests but…

Western Bluebird Chicks in nest
These hungry bluebird chicks will keep their parents hopping!

The nesting season for Western Bluebirds in the Willamette Valley began around April 15 and ended on September 10. Bluebird Trail chair Matt Lee noted that the number of nesting attempts was lower than the average from 2009-2022. There were fewer nesting attempts per box, which could be due to competition with other birds, lack of food, or weather. However, when bluebirds laid eggs in our monitored boxes this year, those nests were about as successful as the nests built during the preceding 14 years.

Western Bluebirds usually take about a week to build the nest once the box is selected. The female lays one per day for a total of four to six eggs. She starts incubating after the last egg is laid, so all of the embryos begin developing at the same time. Hatching happens on the 13th day of incubation. Approximately 19–22 days after hatching, the young fly away (fledge) with one or both parents. More info  Bluebird Lady story

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. Please see Field Trips for registration and more information.
The 2024 Multi-day field trips will be led by experienced birders driving rented vans. Signup sheets are available at monthly meetings starting in January 2024, or click here Info 

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 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.
