The violet-breasted hummingbird inhabits the Andean region in the Cordillera de Mérida in the Venezuelan states of Táchira , Mérida and Lara as well as the Cordillera de la Costa Central in Miranda . Its habitat is wet forests and woodland but also secondary forests and coffee plantations in the lower subtropical zone from sea level to an altitude of 1900 m. Occasionally it is also found in rainforests or cloud forests in the tropical zone.
Way of life
The violet- breasted hummingbird feeds on the nectar of the heliconia flowers. The clutch consists of two eggs that are incubated by the female.
Etymology and history of research
John Gould first described the violet- breasted hummingbird under the name Trochilus (Lampornis) cyanopectus . He named Venezuela as the site. When he introduced the new genus Sternoclyta with the delivery of 16 of his hummingbird tablets , he suggested the species. This name is derived from the Greek words »sternon, στερνον « for »breast« and »klutos, κλυτος « for »splendid, brilliant«. »Cyanopectus« is a structure from the Latin words »cyanos« for »shiny blue, lapis lazuli « and »pectus« for »breast«.
