Introduced from Australia between 1864 and 74 to control pasture pests, magpies were protected until 1951. Two sub-species, the black-backed and the white-backed, were introduced, but the white-backed magpie predominates except in Hawke’s Bay and North Canterbury where up to 95% are black-backed. Magpies are widespread in open farmland with trees or forest, parks and gardens.

This large black and white bird has a pale bluish-grey, black-tipped bill. The song, which is heard especially at dawn and dusk, is a beautiful, flute-like carolling, characterised as ‘quardle oodle ardle wardle doodle’ in Denis Glover's famous poem. Young birds are often heard softly 'practising' their song as they potter around feeding.

The Australian magpie eats a wide variety of invertebrates such as grass grubs, weevils, army worm caterpillars, porina, worms, spiders, ants, flies, crickets and snails. These are supplemented with seeds, grain, small birds, eggs, lizards, mice and carrion. Although magpies are widely assumed to have a detrimental effect on other bird species, there is little evidence for this. Birds and eggs form only a small proportion of their diet and they are opportunistic feeders rather than active predators. They may even help to protect other species by driving away any harriers that appear in their territory.

Breeding takes place between July and December. The nest is a platform of twigs with a cup lined with small twigs, leaves, grass and wool, usually built high in tall trees such as pines, macrocarpas or eucalyptus. The clutch of 2–5 pale bluish green eggs with olive blotches is incubated by the female for 20–21 days. The chicks are fed by both parents and fledge at around 28 days old.  

A pair of Australian magpies frequents the southern part of Tiritiri Matangi. They and their offspring are often seen around the lighthouse area and on Coronary Hill.
