Black-throated Brilliant

The black-throated brilliant (Heliodoxa schreibersii) is a species of hummingbird in tribe Heliantheini of subfamily Lesbiinae. It lives in Brazil, Colombia, Ecuador and Peru. == Taxonomy and systematics == The taxonomy of the black-throated brilliant has not been settled. The International Ornithological Committee (IOC), the Clements taxonomy, and the South American Classification Committee of the American Ornithological Society (SACC) assign two subspecies, the nominate H. s. schreibersii and H. s. whitelyana. BirdLife International's Handbook of the Birds of the World (HBW) treats those taxa as full species, the "black-throated" and "black-breasted" brilliants respectively. In addition, for a time in the early 20th century, the two subspecies were treated as species, the only members of genus Ionolaima, which was subsequently merged into the present Heliodoxa. As of May 2022 the SACC has a proposal pending to resurrect Ionolaima but it has gained little support. == Description == The nominate subspecies H. s. schreibersii of black-throated brilliant is 11.5 to 13 cm (4.5 to 5.1 in) long. Males weigh about 9.9 g (0.35 oz) and females 7.1 to 8.5 g (0.25 to 0.30 oz). Both have an almost straight dark bill about 2.8 cm (1.1 in) long and a small white spot…
