About These Birds
Andean Emerald
A medium-sized hummingbird (9-10 cm) found in Andean cloud forests from Colombia to Peru at 1,000-2,500 m. Green plumage with white breast. Nectarivore of forest edges and gardens. Named after the French naturalist Dr. Francius.
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.
