About These Birds
Black-headed Heron
The Black-headed Heron is a large, stately heron with a black crown and hindneck, gray body plumage, and a contrasting white throat and foreneck. It is widespread across sub-Saharan Africa, inhabiting grasslands, marshes, cultivated land, and open country—often far from water compared to other herons. It feeds on insects, frogs, rodents, and small birds, standing motionless or stalking prey on foot.
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.
