The white-banded sun nymph ( Heliangelus strophianus ) or sometimes also collar sun nymph or gray- bellied nymph is a species of bird from the hummingbird family (Trochilidae). The species has a large range that covers about 10,000 square kilometers in the South American countries of Colombia and Ecuador . The IUCN assesses the population as Least Concern .

features

The white banded sun nymph reaches a body length of about 9.5 centimeters. The straight, black beak becomes about 14 millimeters long. There is a certain similarity to the amethyst sun nymph of the eastern slopes in the Andes. The sexual dimorphism is low. The top is sparkling green. Postocular (behind the eyes) the hummingbird has a rather inconspicuous white spot. Below the neck the hummingbird is green. It turns gray-brown on the stomach. Both sexes have a white or yellowish brown collar. The throat is purple. The dark black tail is 40 to 44 millimeters longer than that of the amethyst sun nymph and is slightly more forked. There is no other colored parting. The whole hummingbird looks relatively dark.

Habitat

Distribution of the white-banded sun nymph

The bird can usually be found in areas with scrub near the edges of the forest. It moves at altitudes between 1700 and 2300 meters. The climatic zone in which the bird can be found ranges from subtropical to colder zones on the western slopes of the Andes. Most reports of sightings of the bird come from Carchi Province to southern Pichincha in Ecuador. One sees in particularly often near the connecting road Mindo and Tandayapa . In Colombia, it is most common in the province of Nariño .

behavior

You can occasionally see the bird on low flowers. Like most sun angels, he likes to spread his wings.

Subspecies

No subspecies of this species are known so far. Thus the white band sun nymph is considered to be monotypical .

Etymology and history of research

John Gould described the white-banded sun nymph under the name Trochilus (——?) Strophianus . Gould did not know the exact location. 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". "Strophianus" is the Latin word for "with a chest band". This in turn comes from the Latin “strophium” or the Greek “strophion στροφιον ” for “chest band”.
