Taxonomy and systematics
editThe white-whiskered hermit is monotypic. The western Colombia population was at one time considered to be a subspecies P. y. sanctijohannis but the description was found to be that of immature birds.[3][4]

Description
editThe white-whiskered hermit is about 13 cm (5.1 in) long. Males weigh 4 to 7 g (0.14 to 0.25 oz) and females 4 to 6.5 g (0.14 to 0.23 oz). This medium-sized hermit has a bronzy crown and iridescent bluish green upperparts. Its underparts are green to dark gray. The face has a black "mask" with a buffy supercilium and a white gular stripe. The male's bill is almost straight. The female has a shorter and gently decurved bill, shorter wings, more grayish underparts, and a longer tail than the male.[4]
Distribution and habitat
editThe white-whiskered hermit is found from Colombia's northern Chocó Department south through western Ecuador to El Oro Province. It has also been reported in Panama near the Colombian border. It inhabits humid mid-elevation and montane forest, humid secondary forest, dense shrublands, and plantations. In elevation it usually occurs below 1,200 m (3,900 ft) but has been recorded as high as 2,000 m (6,600 ft).[4]
Behavior
editMovement
editThe white-whiskered hermit is primarily sedentary but apparently makes seasonal elevation movements in Ecuador.[4]
Feeding
editThe white-whiskered hermit is a "trap-line" feeder like other hermit hummingbirds, visiting a circuit of a wide variety of flowering plants for nectar. It also consumes small arthropods.[4]
Breeding
editThe white-whiskered hermit's breeding season has not been described, though it appears to span from November to July. The nest is a cone-shaped cup suspended from the underside of a drooping leaf. The clutch size is two eggs.[4]
Vocalization
editThe white-whiskered hermit's song is "a continuous series of rather harsh 'kree-u' notes". It also gives a series of "seek" notes while wagging its tail on a low perch at a lek.[4]
Status
editThe IUCN has assessed the white-whiskered hermit as being of Least Concern though its population size is unknown and believed to be decreasing.[1] It is "[g]enerally common in wet forests [but] long-term survival clearly depends on habitat conservation."[4]
