The drop hummingbird reaches a body length of about 11.9 cm, depending on the length of its tail, with the slightly notched tail making up about 4 cm. The wings are approx. 7 cm long. The top, the wing-coverts, the flanks and the tail are shiny green. The white underside has green spots. The blackish under tail-coverts have white borders. There is a small white spot on the post eyepiece. The wings are blackish purple. The black 2.3 cm long beak has a flesh-colored base on the lower beak. The feet are brown. A particularly noticeable sexual dimorphism does not exist, but the coloring appears a bit paler to the females.

behavior

Not much is known about this species' behavior. You can usually see the birds sitting alone on trees in bloom, for example on Inga species. Every now and then they can be seen in groups with various other hummingbird species.

distribution and habitat

Distribution area of ​​the drop hummingbird

In Ecuador they are found on the edges of moist mountain forests and the adjacent forest clearings on the eastern slopes of the Andes from the west of the Napo province to Zamora Chinchipe . The population is densest in the south. Most reports of observations in Ecuador come from altitudes between 500 and 1200 meters. They are also found in Peru on the eastern slopes of the central Andes at altitudes between 750 and 1500 meters. However, it was observed on the upper reaches of the valley of the Río Apurímacin heights of up to 2800 meters. They are also found in central and southeastern Bolivia, in the west of the state of Mato Grosso in Brazil and in northwest Argentina.

Vocalizations

Her call is a mix of a quiet series of whistles, whirring trills and harsh chirps. The soft tones sound like tchit and the whistles like dew dew dew .

Etymology and history of research

John Gould received the type specimen for the first description from Quito . It was probably collected on the upper reaches of the Río Napo . Gould used Aphantochroa hyposticta as the basionyma . It was not until 1910 that Eugène Simon added it to the genus Taphrospilus .

The term »Taphrospilus«, which Eugène Simon introduced in 1910, is derived from the Greek words »terphus ταρφυς « for »ash-colored« and »spilos σπιλος « for »spots«, where »taphros« equals »pit, ditch« by mistake Simon was used. The specific epithet is also of Greek origin and is composed of "hypo- ὑπο " for "below" and "polios στικτος " for "gray".

Pedro Hocking from the Museo de Historia Natural in Lima and Jon Fjeldså may have discovered a new species of the genus Taphrospilus near Abancay . However, this has not yet been named.
