First record of the cf. Rufous-crested Coquette, Lophornis cf. delattrei (Aves, Trochilidae), from Brazil

Abstract

The Rufous-crested Coquette, Lophornis delattrei (Lesson, 1839), and the Spangled Coquette, Lophornis stictolophus Salvin & Elliot, 1873, are 2 very similar species with a green back and orange forehead. On 9 August 2017, a hummingbird with an orange forehead was observed and photographed in the Serra do Divisor (Acre, Brazil). Analysis of the photographs revealed that the individual presented the diagnostic characteristics of a female of the Lophornis delattrei/stictolophus group. We assumed that the observed specimen represented Lophornis cf. delattrei, given the greater proximity of the geographic range of this species to the new locality. The presence of this Lophornis in Acre represents the occurrence of a new hummingbird taxon for Brazil.
