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.

Star

Der Star ist berühmt für seine Schwarmflüge – riesige, wirbelnde Verbände aus Tausenden Vögeln, die am winterlichen Himmel faszinierende Muster bilden. Als geschickter Imitator kann er andere Vogelrufe, Autoalarmanlagen und Handy-Klingeltöne nachahmen. In Nordamerika wurde er von einer Gruppe eingeführt, die jeden von Shakespeare erwähnten Vogel dort ansiedeln wollte.
