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 tiny hummingbird (7-8 cm) found from southern Mexico through Central America to Bolivia and Peru. Males have a rufous crest and wispy cheek plumes. Green plumage. Nectarivore of forest edges, gardens, and clearings. One of the most widespread coquettes.
