[3] The female Psittacula roseata differs with a pale blue grey head and the black neck collar is instead yellow green.

The red shoulder spot is smaller among females, the upper mandible is yellow, and the lower bill is a dark grey.

[3] The different head colour and the yellow tip to the tail distinguish this species from the similar Plum-headed parakeet (H. cyanocephala).

Biswamoy Biswas, an Indian ornithologist, was credited as the authority on this species in 1951 due to his contributions researching the birds of Nepal and Bhutan.

The range expands from Eastern Bangladesh, Bhutan, Northeast India and Nepal, eastwards into Cambodia, Laos, Myanmar, Thailand, Vietnam, and also China.

[4]In 1879, aviculturist Dr. Karl Russ was the first person to record a successful breeding attempt with the Blossom-headed parakeet.

[4] Millet, oats, and canary and sunflower seeds are recommended staple diets for captive Blossom-headed parakeets.

Young parakeets consume a soaked seed mix, green food, and fruit in large amounts.

The Blossom-headed parakeet was classified as near threatened by the IUCN Red List in 2013 because of its moderately rapid decline from trapping and habitat loss.

[12] Human pressures such as agricultural land conversion, hunting, and climate change increase disturbances to Blossom-headed parakeet habitats.

[13] Blossom-headed parakeets commonly frequent farm edges and rural villages in flocks of 20 to 30 birds, causing damage to agricultural crops.
