Red-tailed vanga Calicalicus madagascariensis

Small vanga that is built like a chickadee or tit. Male is colorful and female plain brownish. Madagascar endemic that is found in all forest types, though absent from much of the southwestern spiny forest. Very active and vocal bird that often leads forest flocks. Most common vocalization is a wolf whistle. Separated from Red-shouldered Vanga by its dark eye and less red on the wing. Female very similar to the rare and localized Red-tailed Newtonia, but identified by its larger size, much larger bill, and buffy ring around the eye.
