About These Birds
Annakolibri
Der Annakolibri ist der häufigste Kolibri entlang der Pazifikküste und eine von nur drei Kolibriarten, die ganzjährig in den USA verweilen. Männchen zeigen spektakuläre Sturzflüge aus 40 Metern Höhe und fangen sich mit einem lauten, von den Schwanzfedern erzeugten Zwitschern ab. Nachts kann ihre Körpertemperatur nahezu auf Umgebungstemperatur absinken, um Energie zu sparen.

A medium-sized hummingbird (12-13 cm) endemic to the Atlantic Forest of eastern Brazil. Bronze-green plumage with a hooked bill tip. Nectarivore of forest undergrowth, visiting Heliconia and bromeliads. Classified as Endangered due to severe habitat loss in Brazil's coastal forests.
