About These Birds
Purple-backed Sunbeam
A medium-sized hummingbird (12-13 cm) endemic to a small area in the Andes of northern Peru at 2,900-3,500 m. Purple-backed with buff underparts. Nectarivore of montane scrub. Classified as Endangered due to extremely restricted range. One of Peru's rarest hummingbirds.
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.
