About These Birds
White-tufted Sunbeam
A medium-sized hummingbird (12-13 cm) found in the Andes of Peru and Bolivia at 2,700-4,000 m. Coppery plumage with white breast tufts visible during courtship display. Nectarivore of montane scrub and Polylepis woodland. A Peruvian-Bolivian endemic.
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.
