The emerald- throated sun nymph ( Heliangelus zuii ), also known as the Bogotá sun nymph or emerald- throated nymph , is a cryptic species of bird of unknown origin from the hummingbird family (Trochilidae). It is only known from a museum preparation that was acquired in 1909 in Bogotá , Colombia . The IUCN classifies the species in the category of “insufficient data” ( data deficient ).

features

The emerald-throated sun nymph reaches a body length of about 12 centimeters. The straight, black beak of the only existing specimen is 15.1 millimeters long. The body of the bird is dark black-blue. It has a strongly forked purple tail. The top of the head and the throat are bright green.

habitat

So far there has only been speculation about the habitat of this species. The genus Heliangelus usually occurs in cloud forests and areas with scrub at altitudes between 1,200 and 3,400 meters, but mostly between 1,400 and 2,200 meters. Therefore, it is reasonable to assume that this species also inhabited or inhabited similar habitats.

history

In 1947 the Marist monk Brother Hermano Nicéforo María sent a spectacular taxidermy preparation of a hummingbird to Rodolphe Meyer de Schauensee at the Academy of Natural Sciences of Philadelphia ( ANSP ) with a request for identification. There were heated discussions about the preparation. Often the prevailing opinion was that this had to be a hybrid . James Lee Peters classified the taxon in 1947 as a hybrid between the genera Aglaiocercus and Heliangelus . John Todd Zimmer of the American Museum of Natural History ( AMNH ) said it could be a hybrid of celestial sylph ( Aglaiocercus kingii ) and green- throated sun nymph ( Heliangelus squamigularis ). Alexander Wetmore classified Heliangelus as a separate species in 1947 . Meyer de Schauensee identified it as a possible hybrid of purple glossy tails ( Metallura purpureicauda ) and the hybrid Zodalia thaumasta . Christoph Hinkelmann u. a. synonymisierten Heliangelus zusii 1991 with the invalid today taxon Neolesbia nehrkorni . Also in the South American Classification Committee ( SACC ) there is no clear opinion on the taxonomic status of these hummingbirds. The first attempt in 2003 to withdraw or maintain the species status failed, as did a second attempt in 2007. New DNA analyzes from 2017 show that it is a hybrid.

etymology

"Heliangelus" is derived from the Greek words "hēlios ἥλιος " for "sun" and "angelos ἄγγελος " for "angel, messenger, messenger". "Zusii" is dedicated to Richard Laurence Zusi (1930-).
