Juveniles are mottled gray and white.<p>It perches in a rather upright position, often high on a branch and often staying still for a long time.<p>Though it has some similarities to the northern mockingbird, particularly as to the tail, its dark underparts, shape, size, and behavior are not similar.<p>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 <p>Its song consists of loud, melodious flute-like rising and falling phrases with "low, husky notes interspersed but no distinct pattern" and "a slightly mechanical quality." The call is a squeaky eeek or "clear, soft whistle heeh".
