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.

68 cm. Black and white pied shag; dark forms also occur; orange caruncles. Endemic to Stewart Island and southern South Island coast, New Zealand. Vulnerable; feeds on fish in cold coastal waters. Colonial nester on cliff ledges; closely related to other New Zealand endemic shags.
