Endangered

Olive-winged Trumpeter (Psophia dextralis)


Taxonomy

French: Agami olive German: Olivflügel-Trompetervogel Spanish: Trompetero aliverde oriental
Taxonomy:

Psophia viridis dextralis

Conover

, 1934,

Tauary, right bank of Rio Tapajós, Brazil

.

Closely related to all other congeners. Usually considered conspecific with P. viridis and P. obscura; P. viridis differs in its green middle and lower mantle (3); conspicuous iridescent purple hindneck (2); conspicuous iridescent purple outer wing-coverts (ns[2]); pale bill and legs (3); possibly larger bill (inadequate sample in published manual#R) (ns); P. obscura differs in its dark brown shading to dark green vs mid-brown shading to olive-brown mantle (3); some colour vs virtual absence of colour on hindneck (2); some colour vs virtual absence of colour on outer wing-coverts (2); possibly shorter bill (inadequate sample in published manual#R) (ns). Molecular evidence supports its separation, and also the recognition as a “phylospecies” of the form interjecta (treated as an intermediate population without taxonomic standing in HBW); interjecta is genetically and morphologically close to dextralis, and is here treated as a distinct race#R. Two subspecies recognized.

Subspecies and Distribution
  • P. d. dextralis Conover, 1934 – EC Brazil S of R Amazon (between R Tapajós and W bank of R Xingu).
  • P. d. interjecta Griscom & Greenway, 1937 – NE Brazil S of R Amazon (from E bank of R Xingu to W edge of R Tocantins).
