Little shag - photography by Dr Kerry RodgersThis is smallest shag found in New Zealand. Plumages are highly variable ranging from all black to pied, but all have short stubby, yellow bills (adult), a brown eye and black feet. Adults have yellow facial skin and a small black crest on the forehead. Silent away from their colonies, at the nest they are noisy, making a variety of harsh croaks and whistles. 

Mainly small fish (smelt, bullies, goldfish, flounder, sole) and freshwater crayfish make up their diet.

Little Shags nest in large colonies in trees, low bushes or on ledges, usually near water. The breeding season runs from August to March with a peak in October to November. The nest is a platform of sticks and leaves about 30 cm across. Clutches contain 2–5 pale blue/green eggs, from which 1-3 chicks are usually raised. They are fed on regurgitated food.

Little shag usually feed alone, on small fish, eels, crustaceans; also frogs, tadpole and insects.

They are sometimes seen feeding around Tiritiri Matangi or resting on the rocks, and in 2013-14 they were observed, for the first time, breeding on the Island.
