Overview

Comprehensive Description

The general plumage is green. The breast, abdomen and under tail-coverts are yellowish-green. The forehead is a rich golden yellow. They have a red throat patch to throat. The edge of the wing, lower back and upper tail-coverts are red. The sides to the lower back are yellow. The underside of the flight feathers is greenish-blue. The upperside of the tail is green with greenish-yellow tips. The underside of the tail is greenish-blue. They have a black bill, pale yellowish-white irises and brownish feet. They distinguish themselves from the nominate species (the Orange-fronted Hanging Parrot) by virtue of being slightly larger and the golden yellow is limited to the forehead - while the golden-yellow in the nominate species also extends to the forecrown. The female looks like the male, but her forehead and forecrown are bluish-green with a red base to the feathers. Her cheeks are have a strong blue hue. The throat patch in most females only consists of a few red flecks. Her irises are brown. Young birds look like hens, but without a throat patch. The bill is horn-colored. The Hartert's Orange-fronted Hanging Parrot averages 4.25 inches (about 11 cm) in length. The general plumage is green. The breast, abdomen and under tail-coverts are yellowish-green. The forehead is a rich golden yellow. They have a red throat patch to throat. The edge of the wing, lower back and upper tail-coverts are red. The sides to the lower back are yellow. The underside of the flight feathers is greenish-blue. The upperside of the tail is green with greenish-yellow tips. The underside of the tail is greenish-blue. They have a black bill, pale yellowish-white irises and brownish feet. HABITAT: Moist lowland forests.

Trophic Strategy

Their natural diet consists of nectar, fruits, buds, flowers and seeds. In captivity, their diet should include plenty of fruits, such as figs, pear, apple, banana, and vegetables. They are also fed a seed mix of various millets, canary grass seed, some niger and oats (including sprouted); millet spray; as well as softened rusk, eggfood and meal worm larvae for rearing.

Justification
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Topknot pigeon

The topknot pigeon (Lopholaimus antarcticus) is a pigeon native to Australia. It is also known by the name of flock pigeon.

Description[edit]

The birds are big, with length varying from 40 to 46 centimetres (16 to 18.4 inches). It has a pale grey breast, dark grey wings and a slaty-black tail with one light grey band. The beak is red-brown. The pigeon also has a flattened, wide and sweptback crest of feathers that commences at the beak to the nape of the neck. The crest consists of grey feathers at the front and brown-red feathers at the back. The juveniles are plainer in appearance with a brown bill. The tail band is less defined in the immature.

Habitat[edit]

The topknot pigeon is generally found in groups that can number in the hundreds. They are strong fliers and are often spotted over rainforests and valleys but are also are found around palm trees, figs, eucalyptus forests and woodlands. They are completely arboreal. The birds tend to feed on fruits in the forest canopy and often rest on trees above the canopy. They gain water from raindrops from trees. They are occasionally found in open country seeking food. Birds can often be found from Cape York in Queensland to the South Coast of New South Wales near the coast but have been seen as far south as Tasmania and the Gippsland Lakes in Victoria, depending on food availability. The species were observed in enormous numbers in areas that had rainforest, numbers had declined because of the clearance of these and from shooting, however the increasing prevalence of a new food source in the fruit of the 'weed' camphor laurel trees has seen a recent resurgence in their number. Topknot pigeons are a protected species in Australia.

The birds are rarely heard but seem to produce soft, grumbling grunting noises. They commonly skirmish with each other and when skirmishing, they make short screech noises (akin to a pig).

Breeding[edit]

Breeding occurs from July to January, when nests are usually built in rainforest trees high above the ground. The nests consist of long and loose twigs. One egg is laid that is large and slightly glossy.

Rush Creek, SE Queensland, Australia
