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.
Wire-crested Thorntail
A tiny hummingbird (7-8 cm plus extended tail wires in males, total 12-13 cm). Males have a spectacular erect green crest and long, wire-like outer tail feathers. Found in Andean foothill forests from Colombia to Peru. Nectarivore. One of the most ornate hummingbirds.
