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.
Golden Starfrontlet
A medium-sized hummingbird (13-14 cm) endemic to the eastern Andes of Colombia at 2,500-3,500 m. Males have golden-orange plumage, unusual among Coeligena hummingbirds. Nectarivore of cloud forest. Classified as Endangered due to small range and habitat loss.
