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.
Pale-bellied Hermit
A medium-sized hermit hummingbird (12-14 cm) found in dry forests and scrublands of Colombia, Venezuela, and Panama. Pale belly, green upperparts, and a long curved bill. Nectarivore of dry forest undergrowth and edges. One of the few hermits adapted to arid habitats.
