Agapornis personatus

Geographic Range

Masked lovebirds, also known as yellow-collared or black-masked lovebirds ( Agapornis personatus ) are found in eastern Africa. These lovebirds mainly inhabit Tanzania, southeast of Lake Victoria, with feral populations found in portions of Naivasha, Nairobi and Mombasa, Kenya. These feral populations may have been either intentionally introduced to Kenya or escaped and invaded the area. They are also found in areas outside of eastern Africa due to the large numbers kept in captivity as cage birds around the world, including the United States and Europe.

Habitat

Masked lovebirds live primarily in grassland or lowland savannas, but are also found in woodlands with large numbers of baobab trees and acacias and in inland plateaus. Masked lovebirds require access to water in all habitats and regularly drink several times a day. They commonly occur between 1,100 to 1,800 meters in elevation.

Physical Description

Masked lovebirds are strikingly beautiful, with a green body and a blackish-brown head and mask. They have a black throat with a lemon-yellow chest and collar, grey legs, a coral colored beak and a white ring marking their eyes. Except for the central pair, their tail feathers are mostly green, with a dull orange and blackish band. Their bright yellow collar and black face separate them from other lovebirds. Although masked lovebirds have no sub-species, they do have different color polymorphisms. One of the most recognizable morphs is the blue-masked lovebird, these birds have a deep blue body, white chest and color, and the same blackish-brown head and mask. Other color morphs have been seen but they are not common. This species is relatively small and stocky, with no sizable difference between the males and females. Variation in coloration is not seen between males and females, but is visible between immature and mature birds. Mature adults can range in mass between 30 and 60 grams, with an average mass between 50 and 55 grams. Their wingspan is between 90 and 98 mm, their tail can measure anywhere from 39 to 45 mm and their beak can measure between 16 and 19 mm, the average body length for these birds in 150 mm. Immature masked lovebirds look similar to mature adults, but their head and collar are duller in color.

Reproduction

Masked lovebirds breed in pairs and maintain the same mate throughout their life. This coupling happens early in life, both in the wild and in captivity. During the breeding season, the behaviors of both male and female birds change. Males grow more agitated, while females are busy building a nest to rear young. The appetite of both sexes increases during this time. Males will bring food to the nest and feed their partner during courtship; these birds also preen each other during courtship.

• Mating System
• monogamous monogamous

In the wild masked lovebirds are considered seasonal breeders, they breed during the dry season between the months of March and April, and June and July. They generally have one clutch per season, laying 3 to 8 eggs. In captivity these birds breed year-round. Their average clutch size is 5 to 6 eggs in both captivity and in the wild, with a greater chance of laying up to 8 eggs in captivity. Their incubation period is 23 days. Young lovebirds are largely independent of their parents two weeks after fledging, when they are about 44 days old. Both male and female masked lovebirds reach sexual maturity at 10 months of age.

During the breeding season, females initiate nesting in the hollows of trees. They carry materials, such as strips of bark and long stalks and weave them into a bulky, dome-shaped nest. These nests will maintain their shape, even if removed from the tree cavity. Females may also use the dome-shaped nests of other species in the wild. Egg incubation lasts 23 days. During the first six weeks after hatching, females feed the young until fledging. After the young birds leave the nest, males then take over the feeding of fledglings for an additional two weeks, or until the young birds reach independence.

Lifespan/Longevity

The usual lifespan of masked lovebirds in captivity is 10 to 20 years of age. Their lifespan in the wild is not known.

Behavior

Masked lovebirds are very social. They received their common name, lovebird, because they preen and groom each other, especially their mates. Their pair bonds form early and persist throughout the course of their lives. Masked lovebirds travel mainly by flight and live in small flocks of 4 to 5 birds, but can sometimes be seen in flocks up to 100, although they tend to only move in small flocks, despite belonging to larger groups. While they are rather amiable birds, masked lovebirds can become aggressive with unfamiliar birds or rivals in the wild. In captivity, lovebirds may show signs of aggression when encountering an unfamiliar bird or human.

Home Range

There is currently little information about the home range size of masked lovebirds.

Communication and Perception

Masked lovebirds have a high-pitched twittering call that is used in flight, or when perching, to communicate with conspecifics. One particular call used in the wild is known as the contact call. This is used when flock members want to locate other members and to keep in contact with one another. They usually sing in the morning and evening. Masked lovebirds have a thick, fleshy tongue that allows them to change the sound of their voices and articulate different sounds. This mechanism allows these lovebirds to mimic human voices in captivity; however, it is not particularly common.

• tactile tactile

Food Habits

Masked lovebird eat primarily seeds of trees and grasses including Acacia seeds, millet and sorghum, they also eat tree bark and crops. In captivity, they are fed a variety of seeds as well as mixed vegetables and some fruits.

• Primary Diet
• herbivore herbivore
  • granivore granivore

• Plant Foods
• wood, bark, or stems
• seeds, grains, and nuts
• fruit

Predation

There is currently no known information available on the predation of masked lovebirds.

Ecosystem Roles

The microsporidian parasite, Encephalitozoon hellem , is passed through the fecal matter of birds and is believed to be potentially infectious to humans. Masked lovebirds are 25% more likely to carry this parasite than other birds tested.

Economic Importance for Humans: Positive

Masked lovebirds do not play a major economic role; however, they are kept as cage birds due to their social and amiable behavior.

• Positive Impacts
• pet trade pet trade

Economic Importance for Humans: Negative

Masked lovebirds are considered a crop pest because they feed on millet and corn in fields.

• Negative Impacts
• crop pest

Conservation Status

Masked lovebirds are considered to be of least concern; they are not endangered or threatened at this time.
