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.
Black-throated Hermit
A small hermit hummingbird (9-10 cm) found in humid lowland forests from Colombia to Peru and western Brazil. Dark throat patch contrasting with pale underparts. Nectarivore of forest undergrowth, visiting small Heliconia and Costus flowers along forest streams.
