Taxonomy and systematics
editThe grey-headed piprites is monotypic. It shares genus Piprites with the wing-barred piprites (P. chloris) and the black-capped piprites (P. pileata).[2] The grey-headed and wing-barred piprites form a superspecies.[4]
Description
editThe grey-headed piprites is 12 to 13 cm (4.7 to 5.1 in) long and weighs about 16 g (0.56 oz). The sexes have the same plumage. Adults have a slate-gray head with a bold white eyering. Their upperparts, wings, and tail are olive-green with yellow-green edges on their flight feathers. Their underparts are yellowish olive that is lightest on their throat and belly. They have a dark iris, a blackish maxilla, a paler mandible, and gray legs and feet.[3][5][6][7][excessive citations]
Distribution and habitat
editThe grey-headed piprites is found on the Caribbean slope of Central America from far eastern Guatemala through Honduras, Nicaragua, and Costa Rica to Bocas del Toro Province in far western Panama. It inhabits wet primary forest and mature secondary forest. In elevation it mostly occurs from sea level to 750 m (2,500 ft) though it reaches 1,100 m (3,600 ft) in Honduras and 900 m (3,000 ft) in Costa Rica.[3][4][5][6][7][excessive citations]
Behavior
editMovement
editThe grey-headed piprites is a year-round resident throughout its range.[4]
Feeding
editThe grey-headed piprites forages mostly in the forest's middle level. It feeds on small fruits and insects that it takes with a sally from a perch. It often joins mixed-species feeding flocks.[3][6][7]
Breeding
editNothing is known about the grey-headed piprites' breeding biology.[3]
Vocalization
editThe grey-headed piprites' song is "an undulating two-second phrase of quick, sputtering notes". One call is "a liquid whit!".[7] Another is " a soft, liquid, rolling 'purrr' ".[3]
Status
editThe IUCN has assessed the grey-headed piprites as being of Least Concern. It has a large range; its population size is not known and is believed to be decreasing. No immediate threats have been identified.[1] It is overall considered uncommon to rare and local[3] and rare in Guatemala, Honduras, and Costa Rica[6][7]. It occurs in two protected areas in Costa Rica.[3]
