2-6-2023 BALI BIRD PARK, BALI - LITTLE PIED CORMORANT (Microcarbo melanoleucos)

The little pied cormorant, little shag or kawaupaka (Microcarbo melanoleucos) is a common Australasian waterbird, found around the coasts, islands, estuaries, and inland waters of Australia, New Guinea, New Zealand, Timor-Leste, and Indonesia, and around the islands of the south-western Pacific and the subantarctic. It is a small short-billed cormorant usually black above and white below with a yellow bill and small crest, although a mostly black white-throated form predominates in New Zealand. Three subspecies are recognised. Until recently most authorities referred to this species as Phalacrocorax melanoleucos.

The species ranges across New Zealand, from Stewart Island to Northland, and across mainland Australia (although not in the arid interior of the west of the country) and Tasmania. It is also present in Papua New Guinea, Palau, Timor-Leste, the Solomon Islands, New Caledonia, and Vanuatu. In eastern Indonesia, the little pied cormorant's range includes Sulawesi, the Lesser Sunda Islands, Maluku Islands, and Western New Guinea, with non-breeding birds recorded in Java, Bali, and once off the coast of East Kalimantan. Widespread and common, it lives near bodies of water such as swamps, lakes, lagoons, estuaries and the coastline.

The little pied cormorant is a benthic feeder, i.e. it finds its prey on the sea floor. It is a solitary feeder, normally diving in relatively shallow water, often near the shore. Dive times are short, around 15 to 20 seconds, with recovery times on the surface of 5 to 10 seconds unless prey are being swallowed. It takes a variety of fish prey but an unusually high proportion (nearly 30% by weight on average, and up to 80% in some individuals) of crustaceans. In New Zealand waters it is most often seen preying on the local flounder and other small flatfish. Eels and insect larvae are also consumed. These are brought to the surface to be swallowed: the bird will sometimes put a fish down on the surface of the water in order to re-orient it and swallow it head first. Because of this habit, they suffer some kleptoparasitism from red-billed gulls.
