The buff-bellied hummingbird (Amazilia yucatanensis) is a medium-sized hummingbird. It is 10–11 cm long and has a mass of 4–5 g. Their breeding habitat is forests and thickets that extend from the lower Rio Grande Valley of southernmost Texas in the United States through the Yucatán Peninsula of eastern Mexico, ending in northern Belize and northwestern Guatemala in Central America. It prefers pine-oak forests, semi-arid scrub and thickets along watercourses. The female builds a nest in a protected location such as a shrub or tree. Both males and females of any age aggressively defend feeding locations within his or her territory. Females lay two white eggs.
