I often get asked about bluebirds here in Kitsap County. While a bluebird sighting here would be fairly rare and exciting they are a bit more common in other areas of Western Washington. I ran across the following story on the Tweeters Birding Email Digest. It gives some interesting info about a pair of bluebirds who had a very productive summer out in Sequim.
Amazingly, with the help of lots of mealworms, these two bluebirds proceeded to lay four clutches over the next five months, laying 20 total eggs and fledging 19 chicks. Sara says she put out about 1000 mealworms per week, eventually setting the worms in a special guard by her back door because other birds (Spotted Towhee, WC Sparrow) also started eating the worms. The male bluebird even kicked at the back window at times if the mealworm supply ran out.
