About These Birds
Green-fronted Lancebill
A medium-sized hummingbird (11-12 cm) with a remarkably long, straight bill (40 mm). Green plumage with a violet-blue forehead. Found in Andean cloud forests from Costa Rica to Bolivia at 800-2,500 m. Named lancebill for its dagger-like bill used to pierce the base of long tubular flowers.
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.
