Red-headed Trogon

[order] TROGONIFORMES | [family] Trogonidae | [latin] Harpactes erythrocephalus | [authority] Gould, 1834 | [UK] Red-headed Trogon | [FR] Couroucou a tete rouge | [DE] Rotkopf-Trogon | [ES] Trogon Cabecirrojo | [NL] Roodkoptrogon

Subspecies

Monotypic species

Genus

The trogons are split into three subfamilies, each reflecting one of these splits, Aplodermatinae is the African subfamily and contains a single genus, Apaloderma; Harpactinae is the Asian subfamily and contains two genera, Harpactes and Apalharpactes. Apalharpactes, consisting of two species in the Java and Sumatra, has only recently been accepted as a separate genus from Harpactes. Harpactes is a genus of birds found in forests in South and Southeast Asia, extending into southernmost China. They are strongly sexually dimorphic, with females generally being duller than males. The two members of the genus Apalharpactes are sometimes included in Harpactes.

Physical charateristics

The male has a red head and underparts. Brownish upperparts and black wing-coverts with white vermiculations. The female has a brown head and breast.

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Red-headed Trogon status Least Concern
