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.
Bahama Hummingbird
A small hummingbird (9-10 cm) endemic to the Bahamas. Green plumage with a rose-pink gorget (males) and forked tail. Nectarivore of scrub and garden flowers across the archipelago. The most common hummingbird in the Bahamas.
