Plum-headed parakeet

The Plum-Headed Parakeet

The plum-headed parakeet (Psittacula cyanocephala), also known historically by Latin names such as Psittacus cyanocephalus, is a distinctive species of parakeet native to the Indian subcontinent. It is characterized by its mostly green plumage, with notable differences in head coloration between the sexes. Males sport a vibrant pinkish-purple head that shades to blue-purple on the crown and cheeks, while females have a more subdued bluish-grey head. Both sexes typically have a red shoulder patch and a tail tipped with white or yellow.

These birds are found in a variety of habitats, including forests, open woodlands, and even urban gardens, ranging from the Himalayan foothills down to Sri Lanka. They are not present in the dry western regions of India. Plum-headed parakeets are gregarious and noisy, often seen flying swiftly with rapid twists and turns, accompanied by their characteristic calls. Their diet comprises grains, fruits, and flower petals, and they are known to raid agricultural areas. The species has also been noted for its ability to mimic sounds and talk when kept as pets.

Taxonomy and History

The plum-headed parakeet was first described in 1760 by Mathurin Jacques Brisson, who gave it the Latin name Psittaca cyanocephalos. Carl Linnaeus later included it in his Systema Naturae in 1766. The specific name cyanocephala is derived from Ancient Greek words meaning "dark-blue" and "-headed." The species is now classified within the genus Psittacula. Historically, early accounts of talking birds from India, such as those by Ctesias of Cnidus in the 5th century BC, are believed to refer to this species or a closely related one, highlighting its ancient association with human observation and interaction.

Behavior and Reproduction

Plum-headed parakeets are highly social birds, often found in flocks, and they roost communally. Their flight is swift and agile, marked by frequent twists and turns. The breeding season varies geographically, occurring mainly from December to April in India and from July to August in Sri Lanka. They nest in cavities within tree trunks, which they excavate themselves. Typically, a clutch consists of 4 to 6 white eggs, with the female appearing to be the primary caregiver for incubation and feeding the young.

Distinctive Features and Identification

The primary distinguishing feature of the plum-headed parakeet is the sexual dimorphism in head color. Males have the eponymous plum-like head, while females are grey-headed. A narrow black neck collar and a black chin stripe are present in males, along with a red shoulder patch. The tail is bluish-green and tipped white. The upper mandible is orangish-yellow, and the lower is dark. Females have a duller grey head and lack the distinct black collar and chin stripe, with a corn-yellow upper mandible. Immature birds have green heads and yellowish beaks, developing their adult coloration after about a year. The species is differentiated from the similar blossom-headed parakeet by its head color and white tail tip, as well as the maroon shoulder patch and shorter tail tipped yellow in the latter.
