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, brilliantly colored hummingbird (8-9 cm). Males have a glittering ruby-red crown and golden-orange throat and breast, among the most vivid colors of any hummingbird. Found from Central America to Brazil and Trinidad. Nectarivore of open country, gardens, and forest edges.
