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.
Flightless Cormorant
89–100 cm. Dark brown; vestigial wings unsuited for flight; bright turquoise eyes. Endemic to Galapagos Islands (Fernandina and Isabela). Only flightless cormorant; Vulnerable with about 1,000 pairs. Feeds on fish and octopus by diving near shore; no natural land predators historically.
