About These Birds
Kormoran
Der Kormoran ist einer der am weitesten verbreiteten Seevögel der Welt. Anders als die meisten Wasservögel besitzt der Kormoran kein vollständig wasserabweisendes Gefieder, was zu seiner typischen Haltung mit ausgebreiteten Flügeln zum Trocknen führt. In Asien setzen Fischer Kormorane seit über tausend Jahren zum Fischfang ein.
Double-crested Cormorant
70–90 cm, wingspan 114–123 cm. Dark with two small orange ear tufts in breeding; orange-yellow facial skin. Widespread across North America and Central America. Highly adaptable; colonial nester. Controversial where it competes with commercial fisheries; feeds almost exclusively on fish.
