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 (11-12 cm) found in humid lowland forests from Honduras to Ecuador. Green plumage with a bronze-colored tail. Feathered legs (the plumeleteer trait). Nectarivore of forest undergrowth and edges.
