Subspecies description:
  • Agapornis roseicollis catumbella (Hall,BP 1952) – Brighter colors, with the front of the crown a dark red and the cheeks Bright color.
  • Agapornis roseicollis roseicollis (Vieillot, 1818) – The species nominal
Habitat:

The Rosy-faced Lovebird frequents dry woodlands fields altitudes up to 1.500 m. Sub-desert steppes observed, wooded savannah with scattered forest cover, forest belts along rivers and farmland; often near standing water.

Generally, in flocks of 5 to 20 birds, but sometimes up to several hundred they can gather in areas where grass seeds mature or near water sources.

They are very sociable and noisy, but also pretty tame. When resent, They fly to the nearest tree or vegetation, before returning quickly to the food source.

They used as roosts, nests Sociable Weaver (Philetairus socius) and the White-browed Sparrow-Weaver (Plocepasser mahali). Birds huddle in small groups in branches when the weather is rather cool.

Reproduction:

The Rosy-faced Lovebird can pair off from two months of age. The male wait until the female accepts him before approaching. She takes a stand “uproar” when ready. The male It provides food, while balancing the head to get his attention. Also head scratching, especially around peak. When the male tries his approach, gently slides his hand. You can try out the other side if female It is shown aggressive.

The peach-faced lovebird are monogamous.

Nest in rock crevices, human constructions, bridges or communal nests Sociable Weaver (Philetairus socius) and the White-browed Sparrow-Weaver (Plocepasser mahali). The nest It is made of straw and branches, and some other materials such as bark chips, leaves and herbs, carried by the female rump feathers. The nest of the weavers carries no additional material added. The nests are communal.

The breeding season It has been recorded in the months Feb-Mar, April and October; most seem to be put in the months of February to May.

The female lays 4-6 eggs. The incubation lasts a few 23 days, that alone makes female. It is fed by the male during this period. The chicks are fed by regurgitation female, but it is the male who carries food. The period in the nest It is close to the 5-6 weeks, during which both parents feed the young. Flying around the age of 43 days.

Food:

The Rosy-faced Lovebird they feed on, mainly, seed, sometimes taken directly from the soil, including grasses, Albizia and Acacia; usually they do visits to gardens to feed on sunflower seeds to cropland for him millet and the maize.

Sean is not considered a serious pest for crops because agriculture is scarce in the inhabited regions. They also eat flowers Albizia and other foliage plants, such as leaves of the genus Euphorbia. You can drink several times a day.

Distribution:

Tamaño del área de distribución (reproducción/residente): 774.000 km2

The Rosy-faced Lovebird They are endemic areas southwestern Africa. In Angola, where the range of Rosy-faced Lovebird It is little known, The species is found in the region Sumba (perhaps further north) to the south, in parallel to the shore area through Namibia north of Cape, South Africa, extending from the east to the north. In Namibia to Lago Me, Botswana, Although there are no recent records of the species there.

A sighting 1992 in Victoria Falls, Zimbabwe, suggests little known eastern limits or nomadic behavior.

The main population Rosy-faced Lovebird It is within 400 km of Atlantic coastline. Records in the ancient province of Transvaal They are considered leaks. There is a wild population in the sector Fish Hoek of the Cape Peninsula, South Africa.

Subspecies description:
  • Agapornis roseicollis catumbella (Hall,BP 1952) – Southwest Angola, with a population in the wild Kissama National Park Northwest of Angola.
  • Agapornis roseicollis roseicollis (Vieillot, 1818) – The species nominal
Conservation:

• Current red list of UICN: Least concern

• Population trend: Decreasing

The size of the world population Rosy-faced Lovebird It has not been quantified, but the species is described as locally common or even abundant near areas where water is plentiful.

However it is suspected that the population of the Rosy-faced Lovebird can be in decline due to unsustainable levels of exploitation.

There has been a historic decline due to the capture and export of thousands of birds from Angola, This has contributed, to a large extent, a significant reduction in the population Rosy-faced Lovebird in the south of the country.

In captivity:

The small Rosy-faced Lovebird It is a brilliant bird, Alegre, Robust and gregarious. It is one of the most common parrots in captivity, along with the Budgerigar and Cockatiel, because of its ease of maintenance and reproduction.

Birds are considered easy, ideal for people who want to start raising small parrots. The Rosy-faced Lovebird They can live in a large aviary cage outdoors, including winter. However, They will have to be a haven for frost in the refuge when it is too cold outside.

Are active birds they like to fly. If they have to live in a cage, this will have to be wide and longer than high (birds are not helicopters). Ideally, the bird can time out of its cage in order to be able to fly longer distances.

Contrary to popular belief, the Agapornis well they can live without a partner why sellers try to sell the two, It is a purely financial maneuver. A Agapornis only, will not die.

In the same way, when we say that a Agapornis He will die of sadness when you lose your partner, It is once again a commercial argument. The bird can pass through a period of mourning during which try to call your partner / yy shouts, even more so when the other members of the aviary belong to another species.

All parrots are aves gregarias and they depend on the group to survive. A widow bird accept another partner, previous adaptation before sharing the same cage. It is possible however, two birds never understand (which it is rare, with the Agapornis).
To end this belief, the “couples” of Agapornis They not necessarily have to be of the opposite sex. Homosexual couples are common among Agapornis.

His behavior with birds of their own species is quite good or very good, It is not the same for their behavior with other species: the Rosy-faced Lovebird are restless and vengeful birds. Coexistence with other species is strongly discouraged by the vast majority of poultry farmers: the peak of a lovebird can easily cut your finger or injure another bird, smaller and more peaceful.

In general, the Rosy-faced Lovebird they are birds, relatively, easy to educate, provided that taken from young. Son tame birds, loving, playful, sleepers, large pet birds. The bite related to its small peak is still very painful, especially in the soft fingers of children.

It is permissible to say that males are better pet birds females. The breeding females are often within their hormonal period, making them very territorial. A sweet female domesticated before sexual maturity can be very aggressive to the point of not being manipulated when in hormonal period. Once again, this does not affect all birds, because there are always exceptions.

In general, to the Agapornis, They are not considered good speakers.

Not recommended for people with incompatible squeals.

No sexual dimorphism in this species. The only way to know the sex of the bird is to conduct a DNA test on a sample or a pen clo.

It is not known much about the longevity of the Rosy-faced Lovebird. According to some sources They can live up to 34.1 years in captivity, It is plausible, but it has not been confirmed. Age of sexual maturity of 2 months to almost a year.

Due to the depletion of stocks, in poultry in the early 20th century, It will be started hybridize with other species, but thanks to some breeders are you has been able to preserve in its pure State.

Agapornis roseicollis Mutations
Mutations

Mutations.

There are over 500 mutations or combinations of different colored. Mutations in genes lead to changes in the pigments that give color pens, such as psittacin (red, yellow or orange) or eumelanin (black, brown) or variations on feather structure. They may be sex-linked recessive mutations (They depend on the sex of birds) or autosomal recessive and dominant (irrespective of gender). Among the sex-linked mutations have: ino (known the lutino. There have eumelanin), cinnamon (produce eumelanin brown instead of black), Balls (quantitative reduction of melanin 60 %) andopaline (red psittacine of the mask has spread from the back of the head, the rump is the same color as the body). Also shows some combinations as are the pallidino (Only males, -pallid gene on one X chromosome and ino gene on the other X chromosome) and canela-ino (It is given by crosslinking between cinnamon and ino on the same chromosome and can be male and female). In all these mutations, females never carry the mutation. Years ago, the cinnamon cinnamones were called Americans and Australians palids cinamones or Isabelas.

Consider several crossings (to better understand the sex-linked mutations):

  • Crossing 1: Green x lutino male female = green and lutino male carrying female lutinas
  • Crossing 2: Green male x female = green Lutina carriers lutino males and green females
  • Crossing 3: Green male carrying female green x lutino = green and green lutino male carriers, Green and females lutinas
  • Crossing 4: Green male carrying female lutino Lutina x = green and lutino male carriers lutinos, Green and females lutinas
  • Crossing 5: Lutina x lutino male female = male and female lutinas

As autosomal recessive mutations have:

  • aqua (reducing a yellow psittacine 50 %)
  • turquoise (reducing a yellow psittacine 80-90 %)
  • aquaturquesa (combination thereof)
  • edged dilute (reduction of eumelanin 50 % in the body, in the center of the back and wing feathers eumelanin it is lower than in the edge, it seems that feathers are trimmed)
  • dilute (reduction of eumelanin 80-90 %, having a green veil over the whole body)
  • bronze fallow (It presents grayish brown eumelanin and red eyes)
  • pale fallow (greyish brown eumelanin sparingly, light green eyes and red veil in the abdomen)
  • Harlequin recessive (reduction of eumelanin 95 %, smaller mask)
  • orange face (psittacin mask and tail is orange rather than red)

In these mutations, both males and females can be carriers. To be transmitted, or both are carriers or join a carrier with a mutated. Years ago, to dilute edged was called golden cherry and if it was combined with aqua, aquaturquesa or turquoise, silver cherry o plata.

As we autosomal dominant mutations:

  • dominant pied (reduction eumelanin and randomly scattered throughout the body)
  • pale headed (psittacine of the mask and the tail is light orange pink. Hay SF,factor simple y DF, double factor, ie more or less mask dark)
  • dark factor (a change occurs in the structure of the pen, in the spongy zone, so they look darker. There SF and DF, naming as a factor D and DD for two)
  • purple (a change occurs in the structure of the pen, in the spongy zone. We have SF and DF. The ideal is to combine a dark factor)

As discussed above, both headed as pale as dark violet factor are dominant incomplete, so we say what the single and double factors. In these mutations is mutated or not is, no carriers and being transmitted need only one parent to the present.

Is a Harlequin type which it is transmitted to different recessive and dominant form, is the Harlequin progressive or mottle. The harlequin is increasing as the bird will be more adult, as it is getting older.

The mutation bee does not exist in the A. roseicollis. We have the combination of turquoise with ino, if they go selecting, we can get a completely white bird with red eyes, It would seem albino.

Apart from all these mutations, There is a variety called Long Feathered, of larger size and colors sharper the ancestral. It was obtained through years of selection, It is according to one or arising spontaneously in a aviary, according to others and from there began to work with them. Something similar happened with mandarins (Poephila guttata), Giant calling mandarins. So the variety would call if they have achieved by selection and mutation if they have arisen spontaneously.

Once you view the different mutations must say that several cases can occur, that enable multiple existing color combinations. They may have a recessive mutation with a dominant (edged dilute violeta), two or more mutations at the same time (turquesa edged dilute violeta arlequin DD), and it can even happen to have two different mutations and make the other not appreciated (normal and lutino lutino D or DD are exactly the same visually).
