About These Birds
Short-tailed Emerald
A small hummingbird (7-8 cm) found in Andean cloud forests from Colombia to Venezuela at 1,500-2,800 m. Green plumage with a notably short tail. Nectarivore of montane forest undergrowth and edges. Named for its unusually short tail for an emerald.
Ruby-throated Hummingbird
The ruby-throated hummingbird is the only breeding hummingbird in eastern North America. 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.
