SEPTEMBER 2013 UPDATE
Ups and Downs
2013 marks the 2nd year of post-reintroduction monitoring and our 7th field season on the project. It was an interesting year, full of highs and lows.
Here is a quick summary:
–(A low): 14 Western Bluebirds returned to SJI this year, a marked decrease from the returns in 2012 (34).
– (A high): We had nearly 100% survival rate of nestlings: all birds who hatched survived to fledging, with one exception.
–(A low): 24 nestlings were banded this year, down from 44 in 2012.
–(A high): One of our young females, hatched on SJI last year, flew to Vancouver Island and mated with a male there; the first recorded natural dispersal of these birds since the project began; a male (pictured above) also migrated to Canada.
–(A high): A female from the Ft. Lewis prairie made her way to SJI and mated with a male here, in another demonstration of natural dispersion.
–(A low): Both naturally dispersing females disappeared before young could be raised.
We well recognize that embarking on a project such as this will result in regular triumphs and frustrations. Our plan is to continue the post-reintroduction monitoring of our tenuous population to see if additional measures to augment it will be necessary. Stay tuned!
Fall Bluebird Movement
A common question we get asked is “Where do the bluebirds go in the winter months?”
Our typical response is…”We don’t exactly know.” We do know that usually they depart San Juan Island in October/November (depending on weather conditions). We had a suspected sighting of one of the San Juan population in the Willamette Valley in Oregon this past winter; its possible more go further south, or some may stay close by, potentially on Whidbey Island. Regardless, they aren’t flying as far south as some of the southern populations of Westerns, as they do return quickly; sometimes as early as February.
Now is a good time to look for fall flocking activity, especially on the American Camp prairie and Eagle Cove, False & Kanaka Bay areas.
As always, sighting reports (especially during this time of year, where we are trying to track surviving juveniles) are greatly appreciated.

Spring 2012 Update
With the March winds came the bluebirds, and we are thrilled to see them returning. So far this spring, we have observed 13 pairs of adults (26 birds) on San Juan Island that are actively nesting. Some females are already incubating eggs, others are still building their nests. A few other birds have been sighted but have not been identified just yet.
Especially promising this year is an increase in the number of returning females that were hatched here on San Juan Island. Returning females and a balanced sex ratio are good indicators of a self-sustaining population.
This year Kathleen will be monitoring the populations and we’ll be keeping a careful watch to see how well our initial 5-year effort, with active translocations of birds from Ft Lewis and Oregon, will pay off.
The bluebird project continues north of the border! In an effort to restore Western bluebirds to the entirety of their northern range, two pairs of birds were successfully translocated from Ft. Lewis to The Nature Conservancy Canada’s Cowichan Preserve on Vancouver Island. This is the first translocation of the “Bring Back the Bluebird” project conducted by GOERT (Garry Oak Ecosystem Recovery Team, based in Victoria, BC) which was modeled on our successful project here in the San Juan Islands. Gary Slater of Ecostudies Institute coordinated the translocations. We will be anxiously monitoring to see how our neighbors (neighbours?) to the north carry the legacy of restoring the bluebird to their islands.
The numbers speak for themselves: 92 Adult Western Bluebirds were translocated from the Ft. Lewis, Washington and Willamette Valley, Oregon prairies. 238 baby bluebirds fledged on San Juan Island (possibly even more!). We have a current population size (returning adults) of 38. Over 600 nestboxes were placed on 10 different islands. 376 acres of current/historic oak prairie were permanently conserved. Over 300 community members became involved as volunteers and nest box hosts.
After a 5-year run, the San Juan Islands Western Bluebird Reintroduction Project is wrapping up. We have a lot to celebrate.
- This project marks the first successful reintroduction of a migratory songbird completed in the United States.
- Releases and nest box placement were conducted almost entirely on private lands; nearly unheard of in reintroduction efforts of this sort.
- All of our funding came from individual donors and private foundations; we received no government funding whatsoever for this project.
Although this first phase of the project is “over,” we have more to do. Although the translocations will cease, we will be seeking funding to continue monitoring the population for the next several years to make sure that the numbers of returning and breeding adults continues on its upward trajectory. We will be relying on islanders’ sightings and observations more than ever now that we will no longer have a full-time technician to scout for the birds.
For those who are hosting nest boxes, please remember to clean out your nestboxes each fall and continue to vigilantly remove English house sparrow nests before the young hatch (house sparrows are a distinct and very real threat to bluebirds). Keep those binoculars dusted off and ready to report the first returns in the spring. It will be imporant to continue tracking leg band colors (we know – this can be tricky), as it helps us identify the movements and survival of individuals.
Report any sightings and activity directly to Kathleen Foley at 360-298-1856 or 360-378-2461 (note that the “Bluebird Hotline” number has been disconnected).
These birds have come home. After a long absence of 50+ years, they are now part of our islands and ecosystem again. They will continue to grace our islands only with our help and good stewardship. Please continue to embrace and support their presence here and help us to ensure that they never disappear again. Thank you!

Announcing the San Juan Islands Western Bluebird Reintroduction Project
Project History and Partners
The American Bird Conservancy (ABC) in cooperation with the San Juan Preservation Trust (SJPT), the San Juan County Audubon Society, and the Ecostudies Institute is working to reestablish a breeding population of Western Bluebirds (Sialia mexicana) to areas of their historic range where they have been extirpated in the San Juan Islands. Western Bluebirds were considered common in the San Juan Islands in the 1930s, but extirpated by 1964. Unlike many species, the cause for the decline and regional extirpations of Western Bluebird was less due to loss or degradation of their habitat type (prairie-oak), than it was to loss of a particular habitat element, cavities for nesting. The establishment of nestbox programs to replace the loss of cavities in snags has been used successfully to restore bluebird populations in many areas of North America.
Today, suitable habitat of sufficient size exists on several islands in the San Juan archipelago to support a viable population of Western Bluebirds. Additionally, there has been a considerable amount of oak-prairie habitat conservation implemented through the traditional modes of land protection, habitat management, education and outreach, etc. However, the retraction of the species distribution approximately 100 miles to the south at this northern extent of its range, and the unsuitable nature of the intervening habitat (water and urban/residential) makes it highly unlikely for reestablishment of the species in the extirpated areas through natural recolonization.
There are two goals for the reintroduction project. One is to reestablish a breeding population of Western Bluebirds in the San Juan Islands, Washington and Vancouver Island, British Columbia through the conservation technique of translocating birds from an expanding population on Fort Lewis Military Installation, Washington. Conservation practioners are increasingly relying on species reintroductions as a tool to help reestablish extirpated populations, especially where natural recolonization is unlikely and habitat conservation efforts are ongoing. The project was initiated in Spring, 2007 and will occur over a 5-year time period, the approximate time needed to establish a stable population of reintroduced Eastern Bluebirds to Everglades National Park, a project from which this project is modeled. We will translocate 5-10 pairs of bluebirds each year with a target of approximately 90 adult bluebirds to be reintroduced into the project area.
The second project goal is to use the Western Bluebird reintroduction as a flagship project for community-based education and local participation to support conservation of the entire biodiversity of the highly threatened oak-prairie ecosystem. One of the strengths of this project is the participation and support of local community organizations and individuals. The San Juan Preservation Trust, the San Juan County Audubon chapter, and The Nature Conservancy have pledged in-kind time of their local staff and membership to assist in various aspects of the project including potential release sites, field assistance, bird monitoring, construction of nest boxes and aviaries, and promotion and outreach. Additionally, a number of private landowners on San Juan Island with ideal bluebird habitat on their properties have agreed to provide space for aviaries and nest boxes. The project partners are confident that having individual landowners working in partnership with these conservation groups will ensure the success of this exciting program.
About the Western Bluebird
Physical Description: The Western Bluebird is part of the Turdidae family, which includes robins and thrushes. It is 6-7" (15-18 cm) long, and a long-winged, rather short-tailed bird. Males and females are easily distinguished from one another: the male has deep blue hood and upperparts; rusty red breast and crescent mark across upper back with a white belly. The female is sooty gray above, with dull blue wings and tail. Juveniles look like the female but are grayer, with speckled underparts. Females are attracted by the vivid blue of the male and by the availability of nesting holes. Once the male secures a nesting hole he entices the female with a colorful display that also serves to repel rivals. His rusty breast, like that of the American Robin, is used to signal aggression toward other males.
Nesting: 4-6 pale blue eggs in a grass nest placed in a tree cavity or nest box.
Voice: Soft calls sound like “phew” and “chuck”. Song is a short, subdued “cheer, cheer-lee, churr.”
Range: Breeds from southern British Columbia and western Alberta south to Baja and east throughout the mountains of the West to eastern New Mexico and extreme western Texas. Winters throughout most of breeding range, although northernmost populations usually withdraw slightly southward. The Western Bluebird was once a common breeder and migrant in the San Juan Islands, and could also be found uncommonly as a winter resident. According to Lewis and Sharpe (1987), flocks of these birds were seen migrating on the south and west sides of San Juan Island in the fall and spring, up until 1963. They were “common” on the South side of Mt. Dallas in the 1930’s, and “somewhat common” nesters at Mt. Finlayson and near Deadman Bay. The last reported breeding pair was present on Lopez in 1964. Mountain Bluebirds can still be found rarely in the San Juan Islands, as a migrant or winter visitor.
Habitat needs: Open woodlands, agricultural fields, prairies with abundance of low perching areas, pastureland, parks away from human traffic, cemeteries, golf courses (provided no pesticides are used). Heavily wooded and brushy areas as well as areas where the English House Sparrow are abundant (towns, cities, farmsteads and feedlots) are not suitable bluebird habitat.
Bringing Back the Bluebird: the Reintroduction Plan
Beginning in the Spring of 2007, 4-5 pairs of nesting Western Bluebirds were captured from the large and healthy population of bluebirds at the Ft. Lewis Prairie. These birds were transported to the San Juan Islands. For the first several years of this project, release locations focused on San Juan Valley due to its ideal habitat for bluebirds. Captured pairs were placed in portable aviaries, and left to acclimatize to their new surroundings for several days. During this time they were closely monitored by researchers. After several days, the pairs will be released from the aviaries. At the release locations, and in many other suitable areas around San Juan Island, 250 nest boxes (and counting!) have been placed. Our hope is that the breeding pairs will then establish residence in these nest boxes. Landowners and our summer field technicians keep watch on where the birds go, and report nesting activity. At the end of the nesting season, all boxes/aviaries will be cleaned, and ready to use again for the next season. If all goes well, this process will be repeated for up to 5 years, until a target of 90 bluebirds have been released in the San Juans. Initially, the release sites will be concentrated in San Juan Valley, but if the program is successful, there is potential to expand to other areas in the islands (such as Lopez, where historical records document the presence of breeding bluebirds).
This reintroduction plan is subject to "adaptive management": as we learn from each year's successes and setbacks, plans for the reintroduction efforts may change.
How Can You Help? This project will “fly”, so to speak, only with the help of many, many volunteers. We need people to help construct nest boxes and aviaries, to place the nest boxes, landowners on Lopez, San Juan, Shaw and Orcas Islands to be nest box hosts. Please see our volunteer information sheet for a full description of volunteer needs and to sign up to help.

We need your help! Please report any bluebird sightings to: Kathleen Foley, The San Juan Preservation Trust (378-2461 or email@example.com)
Citizen sightings are critical for us to track the whereabouts of the Western bluebirds that have been released. Even if you are not certain if your sighting is that of a Western bluebird, we would still love to hear from you. Please note that these birds are wearing colored leg bands...this will differentiate them from any other songbird in the region. To report ANY Western bluebird sighting (with leg bands, or without) contact Kathleen Foley at the San Juan Preservation Trust (378-2461) or Barbara Jensen at San Juan Islands Audubon at 378-3068.
