A pair of Eastern Bluebirds brightened up my snowy yard on a gray morning. The specially designed bluebird house installed for them has an opening of exactly 1.5 inches in diameter to ensure that larger birds cannot nest there. Although bluebirds often visit, and occasionally start to build a nest, they never stay through the whole season. After territorial skirmishes sparrows win out. Fingers crossed for this spring!
