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) endemic to the western highlands of Panama at 900-2,000 m. Males have a glowing magenta throat. Nectarivore of cloud forest edges. Classified as Endangered due to extremely restricted range in the Chiriquí highlands.
