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 large hummingbird (12-13 cm) endemic to the coastal mountains of northern Venezuela at 900-2,500 m. Males have a striking violet-blue breast. Nectarivore of montane forest and coffee plantations. A range-restricted Venezuelan endemic.
