Pied Currawongs are omnivorous and opportunistic

Currawongs are medium-sized
passerine birds of the family
Artamidae native to Australasia. There are either three or
four species (depending on whether the Australian Magpie is counted as a currawong or not). The
common name comes from the call of the familiar Pied
Currawong of eastern
Australia and is
onomatopoeic.
The true currawongs are a little larger than the
Australian Magpie, somewhat smaller than most
ravens, but broadly similar in appearance. They are
easily distignuished by their yellow eyes, in contrast to
the red eyes of a magpie and white eyes of Australian crows
and ravens. They are not as terrestrial as the Magpie and
have shorter legs. They are omnivorous, foraging in foliage,
on tree trunks and limbs, and on the ground, taking insects
and larvae (often dug out from under the bark of trees),
fruit, and the nestlings of other birds.
It is sometimes said, with at least some justice, that
the home gardener can have either currawongs or small birds,
but not both—although part of this perception can be traced
to the failure of many gardeners to provide a sufficient
number of dense, thorny shrubs as refuges.
All three currawongs are from the south or east of
Australia.
Pied Currawong
Grey Currawong
The Pied Currawong (Stepera graculina)
is black with white in the wing, undertail covets, the
base of the tail and (most visibly) the tip of the tail.
Size is about 40 to 50 cm. Along with the
Australian Magpie and the
butcherbirds, it has one of the most hauntingly
beautiful caroling calls of any Australian songbird, and
is eclipsed, perhaps, only by the
Grey Shrike-thrush and the
lyrebirds. It is common in woodland, rural and
semi-urban environments throughout eastern Australia,
from
Cape York to western Victoria. It seems to have adapted well to European
presence, and has become more common in some urban areas
such as Sydney.
The Black Currawong (Stepera fuliginosa)
is confined to Tasmania and is all black except for a
small white patch in the wing and a white-tipped tail.
Like all currawongs, it builds a large cup-nest out of
sticks, lined with softer material, and placed in a tall
tree.
The Grey Currawong (Stepera versicolor)
has 6 different races spread right across the southern
part of the continent from the Sydney area south and
west around the coast and hinterland as far as the
fertile south-west corner of Western Australia and the
semi-arid country surrounding it. Outlying populations
are found on the east coast of Tasmania and, oddly, in
the arid area where the Northern Territory meets South
Australia and Western Australia. The races
vary a great deal: the most common mid to dark grey form
(race versicolor) and the grey-brown form of
South Australia, race intermedia, also known as
the Brown Currawong, are readily recognised; the darkest
races, mostly in Tasmania (race arguta, known as
the Clinking Currawong) and the Black winged Currawong
(race melanoptera) from western Victoria's mallee
region, can be difficult to distinguish from the Black
and Pied Currawongs at any distance. Kangaroo Island has
its own race, halmaturina. The race plumbea
occurs from western South Australia west through
southern Western Australia. All Grey Currawongs,
however, have a distinctive ringing call and a more
sharply pointed, finer bill.
Ecology

Unlike many birds, the Currawongs have suffered little
from European occupation of the land. Settlers and
successive generations have replaced much of the natural
woodland and forest with vast artificial grasslands, where
Currawongs are seldom seen. Scattered patches of remaining
bush appear to be sufficient for their needs and the
provision of irrigated waypoints along their rambling
migration routes has encouraged them to take up residence in
areas where they previously only overflew. The effect of
this on smaller birds that are vulnerable to nest predation
is controversial: several studies have suggested that Pied
Currawongs have become a serious problem, but the truth of
this widely held perception remains to be established. They
appear to thrive on berries of some introduced species, some
of which themselves are pests, such as the
Camphor Laurel.
Classification
Currawongs belong to the
subfamilyCracticinae, which also includes the
Australian Magpie and the
Butcherbird: about 20 species in all. Together with the
woodswallows (subfamily Artaminae), they make up the
family
Artamidae, which, in turn, is allied to the
crows and
jays,
fantails,
drongos, and many others. They are Protected in
Australia under the National Parks and Wildlife Act, 1974.
