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.
Dwarf Bittern
The Dwarf Bittern (Ixobrychus sturmii) is a small heron of the family Ardeidae endemic to sub-Saharan Africa. It is the smallest heron found regularly in Africa, measuring approximately 25–30 cm in total length — smaller even than the Least Bittern of the Americas. Adults are dark slate-gray above, including the crown, neck sides, and upperparts, while the underparts are pale buff to whitish with dark brown streaking along the center. The wings show a rufous wing patch visible in flight. …
