Bald Parrot
Pyrilia aurantiocephala

识别特征
The bald parrot is a medium-small, overall green parrot with a bald, brownish-orange head. As several other members of the genus Pyrilia, it has red underwing coverts that barely are visible when perched, but highly conspicuous in flight. The bald parrot communicates with sounds that consist of a high pitched "skee-skee-skee" and a rolling slightly nasal of a "chow-chow-chow". Their diet includes flowers, seeds, fruits, and insects. This medium-sized bird is known for its bare skin and orange head. It has the complexion of intensely orange skin, a paler and more yellow color around the eye, black(ish) coloring around the neck, a mostly green lower neck, light yellow tint to the green wings, and tinged with blue on the lower belly. The unique coloring and baldness of this parrot's head give it its name.
分类信息
This parrot was initially believed to be a juvenile of the vulturine parrot due to the orange coloration of its bald head as opposed to the black of the vulturine. However, when it was discovered that the individuals were sexually mature, they were described as a new species. In reality, juveniles of both species have feathered, greenish heads quite unlike those of the adults. It was formerly placed in the genus Pionopsitta, which is now monotypic.

保护状况
The bald parrot flocks among other parrots, with a population size of 6,700; however, it is decreasing, as the bald parrot continues to be a rare sight for those who can catch a glimpse due to the impact of deforestation in its native habitat. Although 6,700 refers to the estimated number of mature parrots present, an estimated 10,000 Bald Parrots equate to the total population of their species.
