Spotted Shag (Phalacrocorax punctatus)


Taxonomy

French: Cormoran moucheté German: Tüpfelscharbe Spanish: Cormorán moteado
Taxonomy:

Pelicanus [sic] punctatus

Sparrman

Queen Charlotte Sound, South Island, New Zealand

.

Sometimes placed in genus Stictocarbo or occasionally in Leucocarbo. In past, often considered conspecific with P. featherstoni. Considerable variation in prenuptial and nuptial plumages makes definitition of races difficult and uncertain, and species may be better regarded as monotypic. Two subspecies normally recognized.
