Bluebirds are dependent on the open grasslands and oak savannas found in the South Puget Sound. Western Bluebirds have suffered from competition for nest sites because of the introduced European Starlings and House Sparrows. Western Bluebirds feed primarily from perches, dropping to the ground to feed on grasshoppers, caterpillars, beetles, bugs, and spiders. Insects make up about 80 percent of their diet; the rest is fruit, which is consumed from late summer to early spring. As their habitat has dwindled, so too have their numbers. Though not listed as an endangered species, the western bluebird is an uncommon bird in Puget Sound, due to habitat loss and nesting competition by non-native birds.

Update January 2010
Bluebirds are not present at the nest box but with warmer temperatures they may show up early this year and that may mean an early nesting season.  So check often and send our link to other friends and relatives.
