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.
Dot-eared Coquette
A tiny hummingbird (7-8 cm) endemic to central Brazil. Males have spotted ear tufts and rufous crest. Green plumage. Nectarivore of cerrado and gallery forest edges. Named after John Gould. A rare Brazilian endemic; relatively little known ecologically.
