Mountain Bluebird

Mountain Bluebirds are fairly small thrushes with round heads and straight, thin bills. Compared with other bluebirds they are lanky and long-winged, with a long tail.
Male Mountain Bluebirds are sky-blue, a bit darker on wings and tail and a bit paler below, with white under the tail. Females are mostly gray-brown with tinges of pale blue in the wings and tail. They occasionally show a suffusion of orange-brown on the chest. Mountain Bluebirds’ bills are entirely black. Juveniles have fewer spots than the young of other bluebirds.
