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 spectacular small hummingbird (10-11 cm) endemic to the cerrado of central Brazil. Males have two erect, horn-like iridescent violet-blue feather tufts projecting from the sides of the head. Green and white plumage. Nectarivore of cerrado flowers. The only member of its genus.
