Rabo-de-junco Urocolius macrourus

Pale gray bird with an extremely long tail. Note the red bill, red bare facial skin, and glossy blue patch on the back of the head. Main habitat is arid savanna, though also found locally in moister brush and woodland habitats. Always found in groups of five to dozens of birds. The call, frequently given in flight, is a long, mournful “treeeeuw.” Very similar to Red-faced Mousebird, but separated by blue nape and gray rather than buff underparts.
