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.
Straight-billed Hermit
A medium-sized hermit hummingbird (13-15 cm) found in humid lowland forests from Venezuela through Amazonia to Bolivia. Green plumage with a notably straight bill, unusual among hermits. Nectarivore of forest undergrowth. Named after the French naturalist Jules Bourcier.
