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) found in mountain canyons of the southwestern United States and Mexico. Males have a brilliant blue throat gorget. The largest hummingbird breeding in the US. Nectarivore of mountain meadows and garden feeders. Known for its loud, squeaky call.
