Guanay Cormorant
Leucocarbo bougainvilliorum
The guanay cormorant is similar in plumage to the rock shag Leucocarbo magellanicus, but is larger, measuring 71–78 cm from the tip of the bill to the end of the tail, and has more extensive white on the underparts. The bill is grayish with some red at the base. The face is red with a green eye-ring. It has orange-pink feet. The head, neck and back are black, as are the outer parts of the thighs. The throat patch, breast and belly are white. In breeding plumage it has a few white feathers on the sides of the head and neck.

Stewart Island Shag
Leucocarbo chalconotus
The species is dimorphic, with two plumages. Roughly one quarter of the individuals are pied, with dark and white feathers, and the rest, known as bronze shags, are dark all over. Both morphs breed together. These large, chunky birds are about 70 cm long and weigh about 2–3 kg. Stewart Island shags vary in their facial ornamentation in the breeding season. Roughly half of breeding individuals have dark orange papillae on their face, while the other half have small bright orange caruncles above the base of the bill instead.
