Blue-winged Parakeet
Psittacula columboides
The blue-winged parakeet is bluish grey with a long yellow-tipped tail. The black neck ring is complete in both males and females. The male has a bluish-green lower edge to the black collar and the upper mandible is red with a white tip while the female has an all black bill and has only the black collar. The female looks similar to the female of the plum-headed parakeet which however can be told apart by its broad yellow collar. Flocks move through the forest while calling out in a series of screeching keek-keek-keek calls.

Budgerigar
Melopsittacus undulatus
Wild budgerigars average 18 cm (7 in) long, weigh 30–40 grams (1.1–1.4 oz), 30 cm (12 in) in wingspan, and display a light green body colour, while their mantles display pitch-black mantle markings (blackish in fledglings and immatures) edged in clear yellow undulations. The forehead and face is yellow in adults. Prior to their adult plumage, young individuals have blackish stripes down to the cere in young individuals until around 3–4 months of age. They display small, iridescent blue-violet cheek patches and a series of three black spots across each side of their throat.
