Bushtit

The American bushtit's distinguishing characteristics are its tiny size, its plump and large head, and its long tail. Its range stretches from Vancouver in Canada, south through the Western United States, via the Great Basin, the lowlands and foothills of California, the highlands of Mexico, to Guatemala. Bushtits usually inhabit mixed open woodlands, which contains oaks and a scrubby chaparral understory. They can also be found residing in gardens and parks. Their food source is small insects, primarily, and spiders in mixed-species feeding flocks.

The sharp-shinned hawk and other raptors prey upon American bushtits. Bushtits live in flocks of 10 to 40 birds and family members sleep together in their large, hanging nest during breeding season. Once the offspring develop wings that are strong enough to fly, they leave the nest and sleep on branches. Bushtits display a unique behavior as adult males are typically the helpers that assist and raise the nestlings; hence it has intrigued many naturalists for its interesting breeding and mating patterns.
