The pale-tailed hummingbird ( Boissonneaua flavescens ) is a species of bird in the hummingbird family (Trochilidae). The species has a large range that covers about 130,000 square kilometers in the South American countries of Ecuador , Colombia, and Venezuela . The IUCN assesses the population as Least Concern .

features

The pale-tailed hummingbird reaches a body length of about 11 to 11.4 centimeters. The relatively thick beak is about 16 to 18 millimeters long. The top is glossy green. The hummingbird has a rather inconspicuous white spot behind its eyes. The wing bow and the lower part of the wing are colored yellow-brown. The neck sparkles green and becomes shiny on the chest. The belly is gray to yellow-brown and has green speckles. The inner control springs are bronze-green and also turn yellow-brown with bronze spots on the outside.

Habitat

The hummingbird moves in moist forests and forest edges. It can be observed at altitudes of 1500 and 3300 meters. The forests in which the bird is native belong to the subtropical climatic zones. The bird can be found both on the western and eastern slopes of the Andes .

behavior

The bird is relatively territorial in terms of flowers . You can usually find it in the treetops. You can see him deeper in clearings. After landing, it spreads its wings for one to two seconds. He prefers to cling to himself while feeding and also lift his wings. The flowers it flies to are located in the middle and upper areas of the tree canopy. Despite his considerable fighting spirit, he also collects together with other hummingbirds on flowering trees. In the presence of females, the male circles the object of desire. Later he lands near the female and chirps. This later turns into a kind of sums.

Subspecies

Distribution area of ​​the pale-tailed hummingbird

Two subspecies of the pale-tailed hummingbird are known to date:

  • Boissonneaua flavescens flavescens ( Loddiges , 1832)
  • Boissonneaua flavescens tinochlora ( Oberholser , 1902)

The subspecies flavescens is found in northwest Venezuela in the state of Mérida , as well as in Colombia. In addition, it is only present in Ecuador on the eastern slopes near Pan de Azúcar near the Sumaco volcano . The subspecies tinochlora is found in southwest Colombia and the mountain slopes of the western Andes of Ecuador . In Ecuador, it has been observed in the western part of the Cotopaxi province .

Etymology and history of research

George Loddiges originally described the hummingbird under the name Trochilus flavescens . He received the type specimen from the collection of John Gould and it came from Popayán . The bellows that were available to Harry Church Oberholser when describing the subspecies came from the area of ​​the Corazón volcano in the Pichincha province .

The term »Boissonneaua« was given in honor of the ocularist , ornithologist and natural produce dealer Auguste Boissonneau . The Latin epithet »flavescens« comes from »flavus« for »yellow, golden«. The word “tinochlora” is derived from the Greek words “teinō τείνω ” for “to spread” and “khlōros χλωρός ” for “green”.
