Agapornis roseicollis originate in Southwestern Africa in and around Namibia and Angola, its discovered in 1793, its about 15 centimetres long, and typically weighing in at from 50-60 grams. it have a green body color the face is peach colored, its darker in the crown and looks more light under the beak, it have a blue rump and beak have a horn color, and feet are grey.

The young initially have much paler faces than adults. Brighter feathers erupt after their first molt at around 4 months of age. Also, the upper mandible of young birds is black at first, only later becoming the horn-color common in adults.

Roseicollis lives in colonies each one contain from twenty to thirty colony of about hundred birds are not uncommon. . lives in dry regions near permanent standing water. Habitats used by this species include the outskirts of deserts and woodlands, and poorly wooded areas, as long as the few trees are located near water. Preferred regions vary from sea level to elevations over 1500 m.

Movement is primarily by flight, but over short distances these birds prefer to walk or sidle sideways. This species has been recorded flying at 58 km/hr. Long flights are regularly interrupted by periods of gliding. Gliding periods are most often accompanied by a characteristic squawking sound. These birds can climb up vertical walls using feet and beak, often beating their wings rapidly to facilitate movement.

Allopreening and bathing are behaviors observed in these birds, but water bathing in this species is far less common than in other Agapornis species.

When cold, the birds fluff their feathers out and even huddle together in pairs or in groups of 4 or 5 in order to conserve heat.

Agapornis roseicollis sleeps at night and is active in the day. At night these love birds roost in the nests of the white-browed sparrow-weavers or of sociable weavers.


This lovebird makes a sharp screeching noise. This can be given as a single sound or as a series of squawks. This species also can make a soft, rasping mechanical noise by rubbing its mandibles together. Mates communicate for breeding purposes as discussed in the previous section on mating systems, using visual signals like bobbing. These birds also allopreen as a form of communication and to help maintain the pair bond.

Roseicollis shows variability in both nest choice and nest usage. In the wild, these birds commonly breed in the large, communal nests of sociable weavers. They also use the nests of white-browed sparrow-weavers. It is not known if A. roseicollis forces these other birds out of their nests or if they use vacated nests. In captivity A. roseicollis pairs build their own nests. A female prepares strips of bark by cutting them with her beak into relatively uniform shapes and sizes. To carry the bark to the nest site, a female tucks them into the feathers of her rump. Together the male and female build the nest in the shape of a deep cup using bark, leaves, and grass.

roseicollis has been observed to be a seasonal breeder in the wild, but in captivity can breed year-round. Its eggs are typically 23.5 x 17.3 mm. On average, 4 to 6 eggs are laid in one season. In captivity as many as 8 have been laid. Eggs hatch after about 23 days of incubation, and young fledge at about 43 days of age. The young begin to form pairs at around 2 months of age, and also begin to seek their own nests at this time.

Eggs are laid every other day during the breeding season. Beginning when the first egg is laid, a female spends the majority of her time in the nest incubating the eggs. Males often bring their mates food during the period of incubation. The average incubation period is 23.3 days.

After the young hatch, a female regurgitates food brought to her by the male to feed the young. Food that the young eat has therefore been regurgitated twice. Starting midway through the nestling period, which lasts between 5 and 6 weeks, both parents feed the young directly.

Little is known about the behavior of wild A. roseicollis in regards to parental investment after fledging. In captivity, the young remain dependent upon the parents for two more weeks and frequently fly back to the nest to receive food; this happens for as long as the parents permit. When the young leave the nest, after around 42.8 days, they are fully feathered and able to fly.

The typical lifespan in captivity of A. roseicollis is 15 to 25 years. It is not known what limits the lifespan of this species. It is also not known what the typical lifespan in the wild is, although it is likely to be shorter than that seen in captivity.

roseicollis deals with predators by mobbing. As part of their mobbing behavior, individuals initially stand upright and squawk loudly. If the predator moves closer, they flap their wings wildly, holding their bodies erect, and increase their squawking to even higher-pitched squeaks. They also move toward the attacker as if to attack. If the predator does not back down, large groups of birds will attack.

roseicollis has two known parasites. These are the ectoparasites Pellonyssus viator, a mite, and the feather louse Afrimenopon waar Amblycera. Other ways that this species affects its ecosystem are through its interactions with other species of birds, especially the ones whose nests it uses. As a result of its seed-based diet, A. roseicollis probably has some impact on plant ecology.
