The bluebirds have largely disappeared for now. I also haven't seen one in or near the nest box, but I don't have it in easy view. One male was at the front feeder this morning, but that was the first I'd seen this week.
The hermit thrushes have migrated, leaving the 'brown, stripy breast' niche to the brown thrashers. Robins are more in evidence, for some reason--but they're here year-round. Cardinals, occasional house finches, a sparrow or two. A red-bellied woodpecker and a downy woodpecker. And mourning doves doing ground scavenging.
