Inseparable Cachetón

The Black-cheeked Lovebird (Agapornis nigrigenis) they have the forehead, lores and ear-coverts blackish brown with dark brown discoloration on the crown, sides neck and nape, and forming a dark mask.

Mantle, scapulars, rump and uppertail-coverts green. Upperwing-coverts green with bluish suffusion in outer feathers, including alula; vane outside of primaries and secondaries green with bluish suffusion, darker and more green tips; vane grey internal, black at the tips. Underwing-coverts green yellow and green. Chin and front of the throat discoloration to blackish with oxidized orange patch located at the bottom of the throat and top of the breast (bright orange during playback); rest of underparts mostly pale, slightly yellowish, green, bright emerald on flanks and around thighs.

The tail green, except for four outer feathers which show patch of red: Subterminal point dark green in all feathers, except central feathers.

Bill coral red, white at base; iris brown; eye ring White (about 2mm wide); legs grayish brown.

Both sexes similar.

The immature they have the underparts with a wash of dark green; feathers breast and the belly with dark margins. Base bill blackish.

Habitat:

The Black-cheeked Lovebird It is found in woods Mopane (Colophospermum mopane) and Acacias, in the valleys of the rivers altitude between 600 and 1.000 m, adjacent forests Baikiaea plurijuga, of which they are dependent during the wet season. They are also distributed in coastal forests, attracted by the higueras.
Avoid groves miombo Brachystegia.

Generally it is within walking distance of reliable water sources, in small flocks of up to a few dozen birds. You can settle in the community as Lilian's Lovebird.

Reproduction:

The breeding of this species is only known in captivity, but I think you may be similar to the Lilian's Lovebird. Breeding takes place in the months of November-December September perhaps the Victoria Falls.

It is less sociable than other Agapornis, and he dislikes reproduced in Cologne. The female usually puts four eggs, they are incubated for 24 days. The chicks leave the nest to the 40 days of life.

Food:

The need to drink water at least twice a day is a critical determinant of the daily and seasonal activities Agapornis nigrigenis. In the non-breeding season, this species congregate in large flocks of up to 800 birds, reaching peak levels in the early mornings and evenings, when birds drink and feed.

The diet of the Black-cheeked Lovebird It includes seeds, cereals, flowers, buds and berries. Known foods include seeds Amaranthus, Rottboellia high, Rhus quartiniana, Albizia anthelmintica, Combretum massambicense, Syzygium guineense and grasses Hyparrhenia and Eragrostis, also young leaves Pterocarpus antunesii.

Distribution:

The Black-cheeked Lovebird they have a very restricted distribution area (maybe just 6.000 km2), from south Kafue National Park, to the south-west Zambia (only very small numbers), along the valley Zambezi up to the Victoria Falls, Zimbabwe.

Some birds, possibly, also they distributed in the Zambezi region, adjacent to the northeastern end Namibia, for example, Isla Impalila at the confluence of the rivers Zambezi and When; possibly also in the northernmost tip Botswana.

In the dry season, the core areas of forests Mopane totaling only 2.500km2, but the birds are introduced into the fields when crops ripen (causing some damage).

There are some Local movements seasonal.

Many Black-cheeked Lovebird maintained in captivity, above all in South Africa.

Conservation:

• Current red list of UICN: Vulnerable

• Population trend: Decreasing

The population of Black-cheeked Lovebird, based on surveys 1994, It was estimated at about 10,000 individuals, however due to alleged declines in population since then, Today the population can vary within a range between 3,500 and 15,000 birds.

It is believed that three factors have caused the loss of population Black-cheeked Lovebird in the last century:

    – A strong exploitation for cage bird trade from 1920 until the Decade of 1960 (Moreau 1948, Dodman 1995c)

    – The progressive desiccation of their habitat (Moreau 1948, Dodman 1995c), probably the main threat given the highly localized range of the species (Warburton 2003).

    – The partial substitution of crops sorghum and millet, (an attractive source of food).

There is evidence that trade in wild species is currently at a very low level, with isolated incidents and export trade (Dodman 1995c, Warburton y Perrin 2005c), although it is clear that any international demand is met with enthusiasm (Warburton y Perrin 2005a, (d)).

Some birds are captured for consumption and also pursued as pests. Farmers take steps to mitigate the damage to crops, but they are largely ineffective.

Current levels of hunt It is not likely to have a serious long-term impact on the population, but it might endanger local populations suffering from the effects of desiccation.

Recently there may have been local declines due to loss of water supplies shallow in the dry season, perhaps due to climate change in the long term. The number of permanent water sources in forests Mopane It has decreased since the beginning of the century 20. The low availability of water in the dry season It is probably the main factor in the disappearance of permanent populations Bovu and Sinde Rivers, and changes in the population in the Ngweze river. This is compounded by a decrease in annual precipitation in habitat of the species, on average, about 5 mm per year between 1950 and 1995, causing an increase in the dependence of the kind of artificial water sources. The recent creation of hand-pumping wells along the river basins Ngweze, Not chifulo and Machile can lead to a decrease in surface water availability.

In some areas, pools of water are poisoned to kill the fish and this may affect the species.

The species may also be threatened by declining water in the dry season from seasonal rivers in the south-west Zambia, due to decreased levels of rainfall.

Wooded Mopane exploited for firewood and wood, although the habitat is being regenerated and invading other habitats in some areas.

Disease virus beak and feathers They are present in the wild population, but there is no evidence that this is a serious threat.

Conservation actions underway CITES Appendix II.
Proposed conservation actions:
In captivity:

Rare in aviculture. Not easy to find these birds in stores, However, It is quite common among poultry farmers around, and always present in ornithological exhibitions.

The Black-cheeked Lovebird They are less noisy than other species of birds Lovebird; enjoy bathing, They are biting hard, lively and social; They adapt well to life in Cologne, can coexist with birds of the same species and the Lilian's Lovebird (Agapornis lilianae); if space is limited sharing, They can fight each other, although it is generally more peaceful than other species Agapornis; both adult and immature newly imported, They are susceptible first duarnte 10 months; more resistant after acclimatization.

No leaves never completely tame. They do not like the noise, so it is less suitable than others Agapornis life in close contact with man.
