Identification
Bluish-gray upperparts with two white wing-bars. Underside including throat yellow (except undertail coverts and abdomen, which are white); face shows a yellow eye-brow but a white sub-ocular crescent bordered in black. Bill dark but possibly with flesh-colored base, and with flesh-colored legs.

Dry coastal scrublands and, to a lesser extent, moist lowland forests.
