Ruby-throated Hummingbird

The ruby-throated hummingbird is a swift, hovering flower visitor with green upperparts and a slender bill. The male's throat can look dark until light catches the feathers at the right angle. Nectar supplies energy, while small insects and other arthropods contribute nutrients. Females build small cup nests and care for the young. Seasonal migration connects breeding areas in eastern North America with wintering areas farther south.
