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.
Chatham Islands Shag
63 cm. Black and white; orange-red caruncles at bill base. Endemic to Chatham Islands, New Zealand. Critically Endangered; total population fewer than 1,000 birds. Restricted to a few Chatham Islands colonies; feeds on fish and invertebrates in surrounding coastal waters.
