Inseparable rosegorge

Agapornis roseicollis is the scientific name of the Inséparable rosegorge , one of the nine Inseparable species, group of small Perruche S African.

Subspecies and taxonomy

Discovered in 1793, Inseparable the rosegorge was first of all regarded as a subspecies of the Inséparable to red head. This species comprises two tax:

roseicollis (Old-fashioned, 1818) of Namibia and South Africa;
catumbella Hall, 1952 of the south-west of Angola (between the fifteenth parallel and the fifteenth meridian line) in the dry zones which go from the sea up to 1.600 m of altitude.

This subspecies is distinguished from the standard taxon by the coloring redder than pink of the facial mask and by a more important extension of these two colors on the chest, green coloring is also more intense and more brilliant.

The peninsula of the Cape is populated by a population difficult to allot to the one of the two subspecies, perhaps acts it of an intermediate form.

Presenting a very modest circle orbital (in filoplumes and almost unperceivable) and males and females being not easily distinguishable, Inseparable the rosegorge constitutes the transition between the group from the species to white orbital circle (constituted by naked skin) and that of the species with a Net sexual dimorphism.

Distribution

In Angola, Inseparable the rosegorge is not very abundant. It populates the area of Sumba and probably the areas located more at north. This bird is also present in Namibia, in particular in the east around the area of the marshes of Okavango and in the border region with Botswana.

To Zimbabwe, its presence was announced on several occasions close to the Victoria falls. However, because of the complex movements (sedentariness, erratism) of this bird in this country, its surface of nesting is not very defined yet in the east of this state.

Description

The adults do not present a sexual Dimorphisme. They measure 15 to 18 cm and weigh 43 to 63 G. They present a general coloring pale green, a little darker on the upper parts. The tail is blue shining. The face and the top of the chest are pink fishing, from where the name of species. The eyes are russet-red yellowish. The nozzle presents a coloring horn at the black end and a white wax. The legs are gray.

In the young person, the green is paler, it pink of the head more moderate and the nozzle of color chamois with very clear black traces on the higher mandible. The colors of adult appear gradually. Progressively of the growth, it pink pale of the head becomes sharper, it pink of the face moults itself in red and the black marks of the nozzle attenuate then disappear.

Habitat

This bird populates the dry wooded areas (up to 1.500 m of altitude), sparse savannas of large trees, the thickets and the fields. He appreciates the accesses of the rivers.

He generally moves in groups of 10 to 20 individuals but of the bands of a few hundreds of birds can be formed in zones of cultures rich in corn with still milky seeds or meadows having an ear abundance in phase of maturation, or close to particularly abundant sources of water. These last are at the origin of the wandering tendencies of this species.

Reproduction

Inseparable the rosegorge reproduces in isolated couples or colonies. Whatever the mode of nesting, the couples remain very plain. Thus, each one works out a particular language reinforcing its union and making it possible each of the two partners to remain in auditive contact with the other.

Cases of nesting in company of other birds, in particular of plocéidés, are known.

The nest is generally built in the hollow of a tree but this species can also refit the nests out of cut of other birds or use rock anfractuosities. In the absence of such sites, Inseparable the rosegorge is able to build true nests in cupola, by braiding brushwood and grasses.

With pieces of barks chopped and émiettés, the female constitutes a base douillette in the room of incubation.

The season of reproduction generally starts between February and March. It is prolonged until June and July, sometimes even until October.

The female lays 4 to 6 eggs separated by two days, sometimes of only one. The layings from 9 to 12 eggs are however not rare. The incubation, carried out exclusively by the female, lasts 22 or 23 days. The young people leave the nest at the 45 days age, become independent in 2 months and take the delivered adult one around 6 months.

The females reach their sexual maturity between 9 and 11 months and the males between 11 and 13 month.

Changes

Changes of color were observed in a wild state: green more clearly or darker, green plumage scaled of yellow, lutino or pink facial coloring clearly.

In captivity, many Mutation S was selected: Lutino, aqua (blue of sea), turquoise (blue masks white), cinnamon, mixed, pallid (Isabelle), fallow bronzes, fallow pale, orange mask, opaline…

Captivity

Inseparable the rosegorges belongs to the Psittacidae most frequently high because of the facility of their maintenance and their reproduction. They are often advised with the initial stockbreeders because they are robust and can remain the winter outside with the proviso of having a shelter to take refuge.
