CoBirders On the outskirts of the box canyon where I live, in the early fall and early spring, there has been a flock of more than a dozen Western Bluebirds (at least for the past two years). Last summer, we had two breeding pairs. This spring, there is but one, single bird. I keep hoping that more will arrive, but I'm starting to lose that hope.
