About These Birds
Kanadareiher
Der Kanadareiher ist mit einer Höhe von bis zu 1,4 Metern der größte Reiher Nordamerikas. Diese geduldigen Jäger können lange Zeit reglos verharren, bevor sie mit bemerkenswerter Geschwindigkeit nach Beute stoßen. Sie brüten in großen Kolonien, sogenannten Reiherkolonien, und kehren oft Jahr für Jahr an denselben Ort zurück.
Mandarinente
Die Mandarinente gilt weithin als die schönste Ente der Welt. In der ostasiatischen Kultur symbolisiert sie Liebe und Treue, da sie feste Paarbindungen eingeht. Anders als die meisten Enten nistet die Mandarinente in Baumhöhlen bis zu 9 Meter über dem Boden, sodass die erst einen Tag alten Küken zu Boden springen müssen.
