Great billed Parrot


Great billed Parrot

Great billed Parrot is also known as Moluccan parrot or island parrot 33–43 cm. Enormous bill red; head, nape, and mantle bright green, shading to pale blue on back and rump and to yellowish on underparts, with yellow flanks, underwing-coverts, and across undersides of flight-feathers;

scapulars and lesser wing-coverts black, median wing-coverts black-edged yellow; greater wing-coverts and secondaries green edged yellow; primaries blue; tail above green-tipped yellow, below yellowish.

Immature lacks black at the shoulder. Nominate apparently has two types of variation, which has led to the establishment of several supererogatory subspecies:

in one, margins of flight feathers are green instead of blue, (hence “viridipennis” of Tukangbesi, Madu, and Kalaotoa Are, and “djampeae” of Tanahjampea and Kalao, all S of Sulawesi); in other, undersides somewhat greener (again in “djampeae” and in “Floris” of Flores).

Race affinis has bluish tinge to head, green scapulars, lesser wing-coverts greenish-blue; subaffinis like affinis with rump very pale blue, underwing-coverts bluish;

hellmayri like affinis but with yellowish-green head, greener wing covert edges; sumbensis like nominate but head darker green, underparts greener, rump darker blue.

Possibly forms a Moluccan parrot pair with T. lucionensis. Nominate race exhibits much variation, some apparently clinal; now considered to include proposed races viridipennisdjampeaeflorisobiensisbatchianensisfuliginosus and insularum. Five subspecies are currently recognized.
