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.
