Blue-crowned hanging parrot
The blue-crowned hanging parrot (Loriculus galgulus) is a small (length: 13 cm (5.1 in)) mainly green parrot found in forested lowlands in southern Burma and Thailand, Malaya, Singapore, and Indonesia (Sumatra, Java, Borneo).
Blue-crowned hanging parrots are mostly green and the adults have black beaks. Adult males have a blue crown, red throat, red rump, and a yellow lower back. Adult females are duller than males and lack the yellow lower back, usually lack the red throat, and the blue crown is much less noticeable. The juvenile is duller than the female, and has a grey forehead and horn-coloured beak. source
