Red-billed Parrot
Pionus sordidus
The red-billed parrot is 27 to 29 cm (11 to 11 in) long and weighs about 272 g (9.6 oz). All of the subspecies have the eponymous red bill. Adults of the nominate subspecies P. s. sordidus have a dull green head whose feathers have dull blue edges; their eye is surrounded by bare grayish skin. Their back, wings, and inner tail feathers are olive green; their outer tail feathers are blue. Their upper breast is dull blue that becomes buff-olive with a pink tinge on the belly. Their undertail coverts are red. Immature birds have a green head and breast and yellowish green undertail coverts. Voice: The red-billed parrot's flight calls appear to be different among the subspecies. P. s. sordidus and P. s. antelius make "a strident "kee!-yak" ". P. s. corallinus and P. s. mindoensis make "an upslurred "crree!" and a more mellow "crrah" ".
