Mayan antthrush Formicarius moniliger

Elusive inhabitant of humid tropical lowlands and foothills from Veracruz to Honduras. Dark brown and gray overall with pale bluish eyering, darker throat, and rusty rump. Walks jerkily like a small chicken (not like a thrush) on the shady forest floor, holding its tail cocked and tossing leaves with its bill. Can be very difficult to see. Listen for distinctive loud series of piping whistles that drops in pitch.
