Hummingbirds are small birds capable of hovering in mid-air due to the rapid flapping of their wings. They are the only birds that can fly backwards. Unless otherwise noted, all species listed below are considered to occur regularly in North America as permanent residents, summer or winter residents or visitors, or migrants.
Hummingbird females build a nest resembling a small cup about 1.5 inches (3.8 cm) in diameter, commonly attached to a tree branch using spider webs, lichens, moss, and loose strings of plant fibers (image). [14] [15] Typically, two pea-shaped white eggs (image) – the smallest of any bird – are incubated over 2–3 weeks in breeding season.
The tufted coquette (Lophornis ornatus) is a tiny hummingbird that breeds in eastern Venezuela, Trinidad, Guiana, and northern Brazil.

This small bird inhabits open country, gardens, and cultivated areas.
