About These Birds
American Bittern
The American Bittern is a large heron weighing about 735 g with a 54.2 cm wingspan, inhabiting freshwater marshes and reed beds across North America. When threatened, it freezes with bill pointed skyward, its streaked brown plumage blending remarkably with marsh vegetation.
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.
