Only in Mexico. Fairly common small hummingbird of dry coastal scrub in northern Yucatan Peninsula; also very local in dry scrub of central Veracruz. Favors fairly open areas with low scrubby bushes and agave plants. Note the long and slightly arched bill and the long tail, which is usually held closed in a single point. Striking male is distinctive if you are lucky enough to see one. Females and immatures have a distinctive dusky cheek stripe, and usually outnumber adult males by at least 5 to 1.
