About These Birds
Shining Sunbeam
A medium-sized hummingbird (12-13 cm) found in Andean cloud forests from Colombia to Bolivia at 2,500-3,800 m. Coppery-bronze plumage that shines with iridescent sunbeam-like reflections. Nectarivore of montane forest edges and páramo shrubs.
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.
