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.
Bermuda Night Heron
The Bermuda Night Heron was an extinct night heron endemic to Bermuda, known only from subfossil remains recovered from cave deposits. It likely fed on crabs and marine invertebrates in the island's intertidal zones, as its name suggests. It became extinct following the arrival of European settlers and the introduction of predatory mammals.
