The Australian pied cormorant (/ˌpaɪd ˈkɔːrmərənt/ PYD KOR-mər-ənt), Phalacrocorax varius, also known as the pied cormorant or pied shag, is a medium-sized member of the cormorant family. It is found around the coasts of Australasia. In New Zealand it is usually known either as the pied shag or by its Māori name of Karuhiruhi. Older sources may refer to it as the "yellow-faced cormorant".

Range

Pair in Abel Tasman National Park

Auckland, New Zealand

In New Zealand its range on the east coast extends as far south as Christchurch, though this is a recent extension—older books report it no further south than Kaikoura. In Australia it is only moderately common in the eastern states, but abundant in the west.

Habitat

Although typically found in marine habitat—sometimes solitary, sometimes in pairs, sometimes in vast flocks of hundreds or thousands—it is also attracted to inland waters, including lakes, deep and open swamps, and rivers.

Ecology

In flight, Moreton Bay, Australia

The pied cormorant appears to feed largely on benthic fish. It will dive both in shallow, still water and in rapidly moving currents. Typical dive times are around 40 seconds, with a recovery period of 10–15 seconds between dives.
