Sylph Hummingbird: 15 Facts You Won’t Believe!

Sylph hummingbird facts, the long tail feathers on the hummingbirds make flying a lot more cumbersome than it looks

Hummingbirds are part of the family Trochilidae in which thousands of different birds from the genus occur in America. Sylph hummingbirds, with the genus Aglaiocercus, are part of the family of hummingbirds and are found mostly in South America. The genus Aglaiocercus has three different sylph hummingbirds, long-tailed sylph (Aglaiocercus kingi), violet-tailed sylph (Aglaiocercus coelestis), and venezuelan sylph (Aglaiocercus berlepschi). The long-tailed sylph (Aglaiocercus kingi) is the most widespread sylph bird species in the genus and is the only sylph found on the eastern slopes of the Andes, the mountain range in South America that goes through Ecuador, Bolivia, Venezuela, and Colombia. Tandayapa, in Ecuador, is also a hotspot for the violet-tailed sylph.

Sylph hummingbirds are long-tailed South American sylphs with green bodies and glossy purple and blue details on their body and tails. The long-tailed sylph and the violet-tailed sylph are often mistaken for one another as they look quite the same in many aspects, including their blue-green coloration and long tail feathers. However, the male and female species of the birds have some range of differences. Although the long-tailed sylph and the violet-tailed sylph have many similarities in the description, their range of distribution does not normally coincide.

The family of the bird species of hummingbirds is quite large. Read about the hummingbird and the bee hummingbird on the Kidadl website.

The long-tailed sylph is found in subtropical or tropical moist montane forests. The violet-tailed sylph however occurs naturally in low inside forest areas at an elevation ranging from 300-2100 meters. They are found mostly above 900 meters on the west slope of the Andes. They are found close to small clumps of flowers. Venezuelan sylphs are sometimes considered a subspecies of the long-tailed sylph, as they resemble them a lot. The Venezuelan sylph bird is found in forest and scrubland on coastal mountain slopes from 4757-5905 ft (1,450-1,800 m) above sea level.

The males of the species actually have no part in the reproduction process except for the mating ritual with the females. The tail feathers of the males are very long and this is what attracts females towards them. The long tail depicts strength and the female selects the male with the longest tail. Males are known to court the female by flying in front of them in a U-shaped pattern. One male can mate with different female species, and the same thing goes for the females too. The males are not included in the process of choosing the nests or raising the chicks. The average clutch is one egg and the female incubates alone while the male protects the territory and the flowers.

The female feeds the chicks with small insects and the chicks leave the nest in 20 days.

What is their conservation status?

The long-tailed sylph and the violet-tailed sylph are found abundantly in the world, but the population of the Venezuelan sylph is decreasing and the IUCN Red List has categorized this species as Endangered.
