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.
Steinadler
Der Steinadler zählt zu den kraftvollsten und wendigsten Greifvögeln der nördlichen Hemisphäre. Von zahlreichen Kulturen verehrt, wird er seit Jahrhunderten in der Falknerei eingesetzt, insbesondere von kasachischen Adlerjägern Zentralasiens. Bei der Jagd können Steinadler im Sturzflug Geschwindigkeiten von über 240 km/h erreichen.
