About These Birds
Brown Violetear
A medium-sized hummingbird (11-12 cm) with dull brown plumage, unusual among hummingbirds. Found in humid forests from Guatemala through South America to Bolivia. Named for the violet ear patches visible in good light. Nectarivore of forest canopy and edges. Nomadic.
Ruby-throated Hummingbird

These tiny birds beat their wings about 53 times per second and can fly backwards, sideways, and even briefly upside down. They make an extraordinary non-stop 800 km crossing of the Gulf of Mexico during migration.
