I’m pretty confident that the bird in the top of the birch tree is a western bluebird, but I don’t know what the others are. All About Birds from Cornell Lab of Ornithology says that outside the breeding season, they flock in large numbers with several other species of birds, and the flock this morning was huge. They filled the trees and flew among them as Wren raced with delight below. I’m grateful for bluebirds and all the other little songbirds that live here year-round and those who migrate through. I’m happy these birds were enjoying the birch catkins. I hope they’re back tomorrow; I’ll try to get a better view and photos.
