The Purple-crowned Lorikeet ("Glossopsitta porphyrocephala"), also known as the Zit Parrot, is a lorikeet found in scrub and mallee of southern Australia. It is a small lorikeet distinguished by a purple crown, an orange forehead and ear-coverts, and a light blue chin and chest.

Taxonomy

The Purple-crowned Lorikeet was first described by Lionel Dietrichsen in 1837, its specific epithet derived from the Ancient Greek words "porphuros" "purple" and "kephalē" "head".cite book | author = Liddell, Henry George and Robert Scott | year = 1980 | title = A Greek-English Lexicon (Abridged Edition) | publisher = Oxford University Press | location = United Kingdom | isbn =0-19-910207-4] Alternate common names include Porphyry-crowned lorikeet,Lendon, p. 26] Dietrichsen's Lory,Low, p. 116] and Zit Parrot, from its shrill call.Low, p. 117]

Description

Measuring around 15 cm (6 in) long, the male Purple-crowned Lorikeet is a small lorikeet with a dark purple crown, an yellow-orange forehead and ear-coverts, deepening to orange lores, and green upperparts, tinted bronze on the mantle and nape. The chin, chest and belly are a conspicuous powder blue, while the thighs and under-tail coverts are yellowish-green. The green tail has some orange-red coloration at the bases of the lateral feathers. The large crimson patches under the wings are visible when the bird is in flight. The small beak is black, the iris brown and the feet grey. The female is similar but has a darker iris, paler ear coverts and lacks the crimson patches. Immature birds are duller and lack the purple crown.cite book| author=Forshaw, Joseph M. and Cooper, William T. |year=1978| title=Parrots of the World| edition=2nd|publisher=Landsdowne Editions| location=Melbourne| isbn=0-7018-0690-7|pages=p. 90] Its call is a high-pitched loud "tsit", as well as chattering while eating in treetops.

Distribution and habitat

The Purple-crowned Lorikeet is found in southwest Western Australia, and in southern South Australia, east from the southern Eyre Peninsula, through the Gawler Range and southern Flinders Ranges and across Victoria to East Gippsland. It is also found on Kangaroo Island. It is not found in Tasmania.Lendon, pp. 26-27]

Locally nomadic, it is often found in dry sclerophyll forest, especially where "Eucalyptus" trees are flowering.

Behaviour

Generally found in small groups, the species may congregate in larger flocks, and may be in the company of Little- and Musk Lorikeets. It is a fast, straight flyer and dwells mainly in the forest canopy far above the ground.

Feeding

Blossoms of various "Eucalyptus" and "Melaleuca" species, and the boobialla ("Myoporum insulare") are among material consumed.

Breeding

Breeding season is from August to December with one brood laid. The nest is a small hollow in a tree, often with a knot-hole entrance. Sometimes the species nests in colonies. A clutch of 2-4 matte white roundish eggs, measuring 20 x 17 mm, is laid.

Aviculture

Captive Purple-crowned Lorikeets have had a reputation for being short-lived.Lendon, p. 28] It is almost never seen in captivity outside Australia. [Low, p. 118]
