Colombian Mountain Grackle

The Colombian mountain grackle is 27 to 30 cm (11 to 12 in) long. It is slender and has a long tail. The sexes have the same plumage. Adults are almost entirely black overlain with a blue gloss. Their axillaries and underwing coverts are dark chestnut; this color is seldom visible in the field. They have a dark brown iris, a black bill, and black legs and feet. Juveniles are dusky brown with less gloss and chestnut than adults. Voice: The Colombian mountain grackle's song is "variable, sometimes starting with low clicks and buzzing notes, followed by series of different warbled or whistled motifs, each one usually repeated 2–4 times". Its repetitive pattern has been likened to the song of a mockingbird (Mimus). Its calls include "sharp check and chuip notes".
