Chestnut-bellied Hummingbird

The chestnut-bellied hummingbird distribution appears to be restricted to the dryer parts of the Magdalena Valley, Colombia, with a core known range in the Chicamocha, Suárez and Chucurí river valleys. Even though there are now sites where it is known to be found, it is unpredictable in occurrence because of the unknown seasonal fluctuations. It spends the core of its range in dry valleys. Recent records have found it in more humid areas such as the Chucurí near San Vicente de Chucurí and La Paz. Otherwise it has been found in Tipacoque, and a sighting in 2006 at Soatá and has been recorded in five municipalities including a rediscovered population in the environs of Soatá. The sightings seem to be around the range of 850 to 2,200 metres (2,790 to 7,220 ft) above sea level because they like to habituate in places which are usually dry, but due to its current relocating it can now also be found in humid environments as well.

The population is estimated at 3,780 individuals, by extrapolating its known territory size by the area of suitable habitats. However, since many suitable habitats aren't occupied by these and they are not evenly distributed, this may represent an overestimate. The chestnut-bellied hummingbird is located in the dense population region of Colombia. In the past twenty or so years, there has been expansive economic growth, due to a gold rush in 1996 and also the increasingly profitable business of deforestation. Not only are the forests being cut down, but also sugar and coffee plantations are replacing them. Decreased habitats and increased pollution and human migration accompanied these new industries. Although these businesses are benefitting the Colombian economy, they are by far the largest threats to the habitat of the endangered bird.
