The blue-bellied hummingbird ( Lepidopyga lilliae ) is a rare species of hummingbird endemic to Colombia .
description
The male of the blue-bellied hummingbird reaches a size of 8.9 to 9.4 cm and a weight of 4.3 grams. It has a short straight beak. The upper bill is black, the lower bill is pink with a black tip. The top is blue-green, the bottom is deep blue. The throat is iridescent purple. The blue-black tail is deeply forked.
The females have only been observed in recent years. Size and weight as well as the color of the beak are undescribed in the female. The top is glossy green. The color of the tail is green-black. The underside is greyish and heavily spotted. The chest and flanks are glittering blue. The color fades towards the belly and turns into a simple gray towards the lower abdomen and the lower tail-coverts.
Habitat and way of life
The blue-bellied hummingbird is endemic to the mangrove forests and xeromorphic bush vegetation of the Colombian Caribbean coast. Its distribution area extends over the provinces of Atlántico , Magdalena and La Guajira . Most of the observations come from the Isla de Salamanca National Park and from Ciénaga Grande de Santa Marta. His way of life has not yet been adequately researched. Like other hummingbird species, it apparently feeds on insects and flower nectar.
status
In the mid 1970s, an oil pipeline and road were built through the wetlands of Ciénaga Grande de Santa Marta and Isla de Salamanca. This led to the interruption of the natural tidal current and a massive death of the mangrove forests, which lasted until 1992. BirdLife International estimates the population of the blue-bellied hummingbird to be between 50 and 250 specimens. The species was photographed for the first time in 2007. According to the IUCN , the species is classified as Critically Endangered .
Subspecies
No subspecies of the blue-bellied hummingbird are known at the moment. He is considered monotypical .
Etymology and history of research
Witmer Stone described the blue-bellied hummingbird under its current name Lepidopyga lilliae . He named the Punto Caimán in the Sierra Nevada de Santa Marta in Colombia as the site. The type specimen was collected by Melbourne Armstrong Carriker, Jr. "Lepidopyga" is a Greek word structure of "lepis λεπις " for "Scale" and "pygē πυγή " for "rump, rump, buttocks". The epithet "lilliae" devoted Stone his wife Lillie May Stone born Laffert (1872-1940). Stone married her on August 1, 1904.
