Buff-Bellied Hummingbird

The Buff-Bellied Hummingbird (Amazilia yucatanensis) is a medium-sized hummingbird. Their breeding grounds include woodlands and thickets that stretch from the lower Rio Grande Valley in Texas, in the southernmost part of the United States, to the Yucatán Peninsula in eastern Mexico, and on to northern Belize and northwest Guatemala. It favors semi-arid scrub, thickets along watercourses, and pine-oak woodlands. In a safe area, such as a tree or shrub, the female constructs a nest. Aggressively defending feeding areas within his or her territory are males and females of all ages. Every female lays two white eggs.

Adults have an above coloration of metallic olive green and a buffy lower breast. The primary wings and tail are forked and rufous in color. White makes up the underwing. The male's bill is straight and extremely thin. It has a darker tip and is red in color. The throat is a golden-green metallic color. The female is less colorful than the male and has an upper bill that is darker.
