Sulphur-winged Parakeet

The sulphur-winged parakeet is about 23 to 24 cm (9.1 to 9.4 in) long and weighs an average of 82 g (2.9 oz). The sexes are the same. Adults of the nominate subspecies are mostly green. Their head, nape, and throat have some yellow inclusions; bare white skin surrounds their eye and their ear coverts are bright terracotta. Their breast has a dull orange wash. Their wing is mostly green with yellow primary coverts, inner primaries, and outer secondaries; the outer primaries are blue. Their tail's upperside is rufous olive with green fringes on the feathers; its underside is reddish brown. Voice: The sulphur-winged parakeet's most common call is "a series of high-pitched shrill notes, e.g. "krree krree krree" " that is given both from a perch and in flight. It is shrill but not screechy in contrast to that of other Pyrrhura parakeets. Perched birds are often silent. Flocks in flight "call frequently and simultaneously, producing a noisy, harsh and piercing chattering."
