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 small hummingbird (8-9 cm) with a uniquely upcurved, awl-shaped bill. Green plumage with a fiery orange-red tail. Found in humid lowland forests from eastern Venezuela through the Guianas to Amazonia. Nectarivore and insectivore. The only member of its genus.
