Greenish Pufflegs

Hummingbird Information

Greenish Puffleg, Colombia

Greenish Puffleg (Haplophaedia aureliae) The Greenish Puffleg (Haplophaedia aureliae) is hummingbird that occurs naturally in the most southern parts of Central America ranging south to northwestern South America.


Distribution / Range

The Greenish Puffleg is found in Darién region of southeastern Panama (Central America); as well as adjacent areas in the Andes of Colombia and Ecuador (north-eastern South America), potentially south to Bolivia.

They inhabit subtropical or tropical moist montanes and heavily degraded former forest. They are relatively uncommon to rare along the cloud forest borders. They may visit highland gardens and feeders.


Subspecies and Distribution:

  • Based on considerable variations in plumage, several additional races have been proposed:

    The Greenish Puffleg may form a superspecies with the Buff-thighed Pufflegs (Haplophaedia assimilis); some authorities consider the Buff-thighed Puffleg as a subspecies; however, the difference in plumage and geographic separations support their treatment as separate species

        • Haplophaedia aureliae aureliae (Bourcier and Mulsant, 1846) - Nominate Race
          • Range: Eastern Andes of Colombia. Likely also along the eastern slope of central Andes.
          Haplophaedia aureliae caucensis (Simon, 1911)
          • Range: Southeastern Panama and west and central Andes of Colombia.

The Greenish Puffleg has a bronzy-colored head with distinctive small white eye spots. The back is an iridescent green / bronze. The lower chest and abdomen are whitish with some greenish/bronzy spotting. The tail above and below looks dark greyish/bluish.

This species was named for the snow-white dense feathering around the legs known as "leg puffs" (which are not always visible). These leg puffs are unique to the pufflegs and have been described as resembling "woolly panties" or "little cotton balls" above the legs. It has a straight black bill and a forked tail.


Nesting / Breeding

Hummingbirds are solitary in all aspects of life other than breeding; and the male's only involvement in the reproductive process is the actual mating with the female. They neither live nor migrate in flocks; and there is no pair bond for this species. Males court females by flying in a u-shaped pattern in front of them. He will separate from the female immediately after copulation. One male may mate with several females. In all likelihood, the female will also mate with several males. The males do not participate in choosing the nest location, building the nest or raising the chicks.

The female Greenish Puffleg is responsible for building the cup-shaped nest out of plant fibers woven together and green moss on the outside for camouflage in a protected location in a shrub, bush or tree. She lines the nest with soft plant fibers, animal hair and feather down, and strengthens the structure with spider webbing and other sticky material, giving it an elastic quality to allow it to stretch to double its size as the chicks grow and need more room. The nest is typically found on a low, thin horizontal branch.

The average clutch consists of two white eggs, which she incubates alone, while the male defends his territory and the flowers he feeds on. The young are born blind, immobile and without any down.

The female alone protects and feeds the chicks with regurgitated food (mostly partially-digested insects since nectar is an insufficient source of protein for the growing chicks). The female pushes the food down the chicks' throats with her long bill directly into their stomachs.

As is the case with other hummingbird species, the chicks are brooded only the first week or two, and left alone even on cooler nights after about 12 days - probably due to the small nest size. The chicks leave the nest when they are about 20 days old.


Diet / Feeding

The Greenish Pufflegs primarily feed on nectar taken from a variety of brightly colored, scented small flowers of trees, herbs, shrubs and epiphytes. They favor flowers with the highest sugar content (often red-colored and tubular-shaped) and seek out, and aggressively protect, those areas containing flowers with high energy nectar.They use their long, extendible, straw-like tongues to retrieve the nectar while hovering with their tails cocked upward as they are licking at the nectar up to 13 times per second. Sometimes they may be seen hanging on the flower while feeding.

Many native and cultivated plants on whose flowers these birds feed heavily rely on them for pollination. The mostly tubular-shaped flowers actually exclude most bees and butterflies from feeding on them and, subsequently, from pollinating the plants.

They may also visit local hummingbird feeders for some sugar water, or drink out of bird baths or water fountains where they will either hover and sip water as it runs over the edge; or they will perch on the edge and drink - like all the other birds; however, they only remain still for a short moment.

They also take some small spiders and insects - important sources of protein particularly needed during the breeding season to ensure the proper development of their young. Insects are often caught in flight (hawking); snatched off leaves or branches, or are taken from spider webs. A nesting female can capture up to 2,000 insects a day.

Males establish feeding territories, where they aggressively chase away other males as well as large insects - such as bumblebees and hawk moths - that want to feed in their territory. They use aerial flights and intimidating displays to defend their territories.
