Its plumage is mostly bright yellow, hence its common name, but it also possesses green remiges. It lives in the drier, upland rainforests in Amazonian Brazil, and is threatened by deforestation and flooding, and also by the now-illegal trapping of wild individuals for the pet trade. It is a protected species listed on CITES appendix I.
Description
The Golden Parakeet is mainly yellow with green in outer wings and with an all-yellow tail. It has a large horn-coloured beak, pale-pink bare eye-rings, brown irises, and pink legs. Male and female have identical external appearance. Juveniles are duller and have less yellow and more green plumage than the adults. The juvenile's head and neck is mostly green, the back is green and yellow, the upper side of tail is mostly green, the breast is greenish, the eye-rings are pale-grey, and the legs are brown.
Distribution and habitat
The Golden Parakeet is distributed in the northern parts of Brazil. The birds studied for a 1986 study used two different habitats during the year; during the non-breeding season, which coincided with the dry season, they occupied the tall forest. During the breeding season they left the tall forest and entered open areas on the edge of the forest such as fields used in agriculture.
Behavior
Golden Parakeets are a sociable species, living, feeding, sleeping and even breeding together. They eat fruits, flowers, buds, seeds, and cultured maize in the wild. These include the seed of Croton matouensis, which is related to the castor bean plant; Muruci fruit (Byrsonima crispa); mangoes; and Açaí fruits.
Reproduction
The Golden Parakeet has a breeding system that is almost unique amongst parrots, as pairs are aided by a number of helpers which aid in the raising of the young. This behavior is less common with parakeets in captivity, who often abandon their young after three weeks.
After the Golden Parakeet reaches sexual maturity at the age of three years, the breeding season starts in November and runs through February. They nest in a high tree, in deeper than average nesting cavities, and lay an average of four 37.1 x 29.9 millimeter eggs, which they aggressively guard. The incubation period is about 30 days, in which the male and female take turns incubating. In the first few years of sexual maturity, Golden Parakeets tend to lay infertile clutches until the age of six to eight. In captivity, Golden Parakeets will resume breeding when their chicks are taken from them.
At birth, Golden Parakeets are covered in white down that eventually turns darker within a week. By the end of the third week, wing feathers start to develop. Juveniles are playful, but may turn abusive against their peers. Nestlings are preyed upon by toucans, a fact that may explain their social behaviour. Nests are vigorously defended from toucans by several members of the group.
Conservation
The Golden Parakeet is listed on the IUCN Red List as endangered. This is largely due to deforestation and the capture of wild birds for aviculure, where in high demand due to the attractiveness of its plumage. Locally, they are considered as pests for feeding on crops, and are hunted for food or sport.
An example of the displacement of Golden Parakeets by habitat loss comes from the building of the Turucuí Dam, Pará, from 1975-1984. More than 35,000 forest dwellers were forced from what had been a habitat that was considered to be "among the richest and most diversified in the world." In addition, 2,875 square kilometers of rainforest were flooded, and 1600 islands were produced by the flooding, all of which were heavily deforested.
