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.
Peruvian Piedtail
A small hummingbird (9-10 cm) found in Andean cloud forests of Peru at 1,300-2,200 m. Green plumage with pale-tipped tail. Nectarivore of montane forest understory. Named after Ernst Hartert. Classified as Near Threatened due to limited range.
