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.
Short-tailed Woodstar
A tiny hummingbird (6-7 cm), one of the smallest birds in the world. Found in arid coastal Peru and Ecuador. Short tail, short bill, and tiny body. Nectarivore of desert scrub and dry woodland flowers. Weighs only 2-3 grams.
