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.
Minute Hermit
A tiny hermit hummingbird (6-7 cm), one of the smallest in its genus. Endemic to the Atlantic Forest of eastern Brazil. Green plumage with rufous underparts and a short, curved bill. Nectarivore of low forest undergrowth. Classified as Near Threatened due to habitat loss.
