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 montane forests from Venezuela to Bolivia at 1,000-2,500 m. Green plumage with a rufous breast. Thickened outer primaries. Nectarivore of cloud forest undergrowth, visiting Heliconia flowers.
