Verbreitung und Lebensraum

The hoary puffleg is found in a fairly narrow band on the Pacific slope of the Andes, from southwestern Colombia's Nariño Department south into Ecuador as far as Pichincha Province. It inhabits cloudforest, the borders of other types of tropical and subtropical forest, and scrublands. It tends to stay in low dense vegetation, often near streams. In Colombia it has been recorded between elevations of 1,200 and 2,000 m (3,900 and 6,600 ft) and locally as high as 2,500 m (8,200 ft). In Ecuador records span from 1,525 to 2,100 m (5,000 to 6,900 ft).

Resident species

Verhalten

The hoary puffleg is a year-round resident throughout its range.<p>The hoary puffleg forages for nectar mostly near the ground but occasionally in the canopy. It is territorial and defends clusters of flowers. It typically feeds on flowers with short corollas such as Besleria sp., Palicourea sp., Thibaudia sp., Melastomataceae, and Marantaceae. In addition to nectar, it feeds on insects that it gleans from leaves.<p>The hoary puffleg's breeding season has not been well defined, but nesting has been recorded in May and August. The nest is a hanging cup or ball made of moss and spiderweb; it is attached to the underside of a fern or other large leaf that protects it from rain. It is typically 0.5 to 2 m (2 to 7 ft) above the ground. The female incubates the clutch of two white eggs for 15 to 17 days and fledging occurs 20 to 24 days after hatch.<p>Only one hoary puffleg vocalization has been described, "a single strident 'tzik' or doubled 'tsi-tsik', repeated at irregular intervals". It is given both from a perch and in flight.
