Jason Cho encountered and photographed a Blossom-headed Parakeet (Psittacula roseata) at Singapore’s Pasir Ris carpark in October 2007.
This is a resident of NE India, Bangladesh, SW and S China. In Southeast Asia it is uncommon to fairly common in Myanmar, parts of Thailand and Indochina.
There is a substantial international trade in this parakeet. This specimen is most probably an escapee.

This post is a cooperative effort between NaturePixels.org and BESG to bring the study of bird behaviour through photography to a wider audience.
Note: Lee Chiu San believes the bird is a Plum-headed Parakeet (P. cyanocephala), see under comment.
