The green ribbon sun nymph ( Heliangelus exortis ) or tourmaline sun nymph is a species of bird from the hummingbird family (Trochilidae). The species has a large range that covers about 64,000 square kilometers in the South American countries of Colombia and Ecuador . The IUCN classifies the population as “not at risk” ( least concern ).
features
The green band sun nymph reaches a body length of about 8.5 to 10.2 centimeters. The straight, black beak becomes about 15 millimeters long. The entire upper part of the male is glossy green. The forehead stands out from this in color with a shimmering green. Postocular (behind the eyes) the hummingbird has a rather inconspicuous white spot. The chin is glittering purple-blue and becomes pink-purple towards the lower neck. The belly is gray and turns white towards the lower part (crissum). The relatively long forked tail is predominantly black-blue. The inner control springs are bronze green. The female varies somewhat in color. The top resembles that of the male. Some of the females have contrasting white throats. Others have throats similar in color to the male. The rest of the base is a mix of dark white and green. The tail is very similar to that of the male. It is a bit shorter and is not forked as much.
Habitat
You can see the hummingbird mainly on damp to wet forest edges, bushy clearings, scrubby pastures and hedges. It is present at altitudes between 2200 and 3100 meters.
behavior
The bird gets its food mainly from flowers. In doing so, it clings temporarily and spreads its wings. When foraging for food, it preferably moves in low bushes. The bird is very territorial . In Ecuador, it can often be seen in Morona Santiago on the Río Palora in the Sangay National Park . It is also found in Ecuador on the eastern slopes of the Andes. In Colombia you can find it in Putumayo .
Subspecies
No subspecies of the tourmaline sun nymph are known at the moment. The species is therefore considered to be monotypical .
Etymology and history of research
Louis Fraser described the green band sun nymph under the name Trochilus exortis . He received the type specimen with a delivery consisting of 18 bellows from Santa-Fé de Bogota . He named Guaduas in the Departamento de Cundinamarca in Colombia as the site. It was later assigned to the genus Heliangelus . This name is derived from the Greek words "hēlios ἥλιος " for "sun" and "angelos ἄγγελος " for "angel, messenger, messenger". "Exortis" comes from the Latin "exortus, exoriri" for "dawn, east, rise".
