The blue-capped puffleg (Eriocnemis glaucopoides) is a species of hummingbird in the "brilliants", tribe Heliantheini in subfamily Lesbiinae. It is found in Argentina and Bolivia. [3] [4]

Contents

Taxonomy and systematics

The blue-capped puffleg is monotypic. [3]

Description

The blue-capped puffleg is 9 to 13 cm (3.5 to 5.1 in) long and weighs 4.0 to 4.5 g (0.14 to 0.16 oz). It has a straight black bill. The male has dark green upperparts with a dark glittering blue forehead. Its underparts are mostly golden green, with a bluish green lower breast and shining purplish blue undertail coverts. Its leg puffs are white. The tail is long, forked, and blue-black. The female's upperparts are also dark green but without the blue forehead. Its throat, breast, and belly are bright cinnamon-buff and the undertail coverts have pale buff fringes. The female's tail is less deeply forked than the male's. [5]

Distribution and habitat

The blue-capped puffleg is the southernmost representative of its genus. It is found from Bolivia's La Paz and Cochabamba departments south into northwestern Argentina's Salta and Tucumán provinces. It generally inhabits humid slopes of grass and dense shrubs and the edges of cloudforest. In Argentina it also occurs in somewhat dryer landscapes. In elevation it ranges from 1,500 to 3,400 m (4,900 to 11,200 ft) but is most common between 2,000 to 2,500 m (6,600 to 8,200 ft). [5]

Behavior

Movement

The blue-capped puffleg is generally sedentary. However, it is known to make seasonal elevational movements in Argentina and suspected to do so in Bolivia. [5]

Feeding

Almost nothing is known about the blue-capped puffleg's diet or feeding behavior. It has been observed taking nectar from low-growing plants. [5]

Breeding

The blue-capped puffleg has been documented breeding in November in Bolivia but little else is known about the species' breeding phenology. The female inclubates the clutch of two eggs but the incubation period and time to fledging are not known. [5]

Vocalization

The blue-capped puffleg's vocalizations are not well known. As of early 2022, Xeno-canto and Cornell University's Macaulay Library each had a single recording. The only description of the vocalization is "a high-pitched 'zee-zee'". [5]

Status

The IUCN has assessed the blue-capped puffleg as being of Least Concern. Though its population size is not known it is believed to be stable, and no specific threats have been identified. [1] It is considered overall to be rare but locally common and occurs in two national parks in Argentina. [5]

<span class="mw-page-title-main">Turquoise-throated puffleg</span> Species of bird

The turquoise-throated puffleg, also known as Godin's puffleg, is a species of hummingbird from Ecuador. It is mostly green with blue undertail coverts and white powder-puffs of downy feathers on the legs, and the male has a bluish-purple throat patch. It is only known from a few specimens taken in the nineteenth century and its taxonomic position is unclear. The type of habitat in which the type species was obtained has largely disappeared, and recent surveys trying to find this bird have failed. The International Union for Conservation of Nature believes it may be extinct, but there is a possibility that some individuals remain, so the bird has been rated as "critically endangered".

Puffleg Hummingbird

The pufflegs are hummingbirds from the genera Eriocnemis and Haplophaedia. They occur in humid forest, woodland and shrub at altitudes of 1000 to 4800 m. asl in the Andes of Argentina, Bolivia, Peru, Ecuador, Colombia, and Venezuela. The males have a colorful green, coppery or blue plumage, and the females are generally somewhat duller. The most striking feature of both sexes is their dense snow-white leg puffs which consist of feather tufts that resemble woolly panties. One species - the black-thighed puffleg - is characterized by black coloured leg puffs, and another - the buff-thighed puffleg - has lightly buff-tinged leg puffs. Further common features of all species are the straight black bill and the slightly to deeply forked tail. The members of the genus Haplophaedia are generally duller than the members of Eriocnemis.

<i>Eriocnemis</i> Genus of birds

Eriocnemis is a genus of hummingbirds, which - together with the species in the genus Haplophaedia - are known as pufflegs. They occur in humid forest, woodland and shrub at altitudes of 1000 to 4800 m. asl in the Andes of Argentina, Bolivia, Peru, Ecuador, Colombia, and Venezuela. The males have a colourful green, coppery or blue plumage, and the females are generally somewhat duller. The most striking feature of both sexes in the genus Eriocnemis are their dense snow-white leg-puffs which consist of feather tufts that resemble woolly panties. One species, the black-thighed puffleg - is characterized by black coloured leg-puffs. Most have a contrasting blue, purple or coppery-red vent, but this is green in the black-thighed and emerald-bellied puffleg. Further common features of all species are the straight black bill and the slightly to deeply forked tail. The genus name was coined by the German naturalist Ludwig Reichenbach who called them Snowy panties.
