Rufous-shafted Woodstar

The rufous-shafted woodstar (Chaetocercus jourdanii) is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is found in Colombia, Trinidad and Tobago, and Venezuela. == Taxonomy and systematics == The rufous-shafted woodstar was formally described in 1839 by the French ornithologist Jules Bourcier based on specimens collected in Trinidad. Bourcier placed the new species in the genus Ornismya and coined the binomial name Ornismya jourdanii. The species is now placed in the genus Chaetocercus that was introduced in 1855 by the English zoologist George Robert Gray with the rufous-shafted woodstar as the type species. The genus name is a combination of the Ancient Greek words khaitē, meaning "hair" and kerkos, meaning "tail". The specific epithet was chosen by Bourcier to honour the French zoologist Claude Jourdan. Three subspecies are recognised: C. j. andinus Phelps, WH & Phelps, WH Jr, 1949 – northeast Colombia and west Venezuela C. j. rosae (Bourcier & Mulsant, 1846) – north Venezuela C. j. jourdanii (Bourcier, 1839) – northeast Venezuela and Trinidad == Description == The rufous-shafted woodstar is 6 to 8 cm (2.4 to 3.1 in) long. Both sexes of all subspecies have a straight black bill and white patches…
