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) found in Andean cloud forests of Peru and Bolivia at 1,500-2,800 m. Green plumage with rufous webbing on wing feathers visible in flight. Nectarivore of montane forest. Named for the rufous inner web of flight feathers.
