About These Birds
Tapajos Hermit
A small hermit hummingbird (10-11 cm) found along the Tapajós River basin in central Brazil. Green plumage with rufous underparts. Nectarivore of forest undergrowth. Recently described as a species distinct from other Phaethornis hermits based on vocal and plumage differences.
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.
