Hummingbirds (Trochilidae)

Hairy Hermit (Glaucis hirsuta) - HBW 5, p. 538

French: Ermite hirsute German: Rotschwanz-Schattenkolibri Spanish: Ermitaño Hirsuto
Other common names: Rufous-breasted Hermit

Taxonomy: Trochilus hirsutus J. F. Gmelin, 1788, north-eastern Brazil.
Sister species of G. aenea, and these two often considered conspecific, but they meet in W Panama and W Colombia without interbreeding; present species interrupts former probably continuous distribution of G. aenea and presumably in gradual process of replacing it. Several attempts have been made to subdivide present species into races, with affinis of the Guianas, mazeppa of CE Brazil, and abrawayae of SE Brazil; these were based on plumage differences in immature and adult males and females, but did not take into consideration intraspecific variation in co..

Taxonomy: Trochilus hirsutus J. F. Gmelin, 1788, north-eastern Brazil.
Sister species of G. aenea, and these two often considered conspecific, but they meet in W Panama and W Colombia without interbreeding; present species interrupts former probably continuous distribution of G. aenea and presumably in gradual process of replacing it. Several attempts have been made to subdivide present species into races, with affinis of the Guianas, mazeppa of CE Brazil, and abrawayae of SE Brazil; these were based on plumage differences in immature and adult males and females, but did not take into consideration intraspecific variation in coloration and measurements independent of geography; only birds from Grenada, Trinidad and Tobago are morphologically separable. Includes “Threnetes grzimeki”, based on immature male plumage. Two subspecies currently recognized.

Subspecies and Distribution:

  • insularum Hellmayr & von Seilern-Aspang, 1913 - Grenada, Trinidad and Tobago.
  • hirsuta (J. F. Gmelin, 1788) - Panama, Colombia W of the Andes, and E of the Andes S to C Bolivia, and through Venezuela to the Guianas and almost all of Brazil.
