Mountain Bluebird

Mountain Bluebird Identification
These colorful songbirds can easily be identified by their bright blue overall plumage, but wear and tear on their feathers can make coloring uneven and birders should know other key field marks to be certain when they see mountain bluebirds. Males are significantly brighter than females, but their underparts are duller and gray-blue or whitish on the lower abdomen and underneath the tail. A gray wash can be seen around the lores and eyes and could create a faint mask-like appearance.
