What is townsend's Solitaire?

Townsend's solitaire reaches a length of approximately 8–9.5 inches (20–24 cm) and wingspan of 14.5 in (37 cm); it weighs approximately 1.2 oz (34 g). It has a short, thick, blackish bill; a white eye ring; and gray plumage with a buffy wing stripe and edges of the flight feathers. The tail is long, tapered when shut, and edged with white. Juveniles are mottled gray and white. It perches in a rather upright position, often high on a branch and often staying still for a long time. Though it has some similarities to the northern mockingbird, particularly as to the tail, its dark underparts, shape, size, and behavior are not similar. It feeds primarily on berries and insects. The solitaire is amongst the most specialized of all North American birds since its diet in winter consists almost entirely of the fleshy cones of the juniper bush, and the solitary birds form territories around productive juniper patches which they strongly defend
