Taxonomy and systematics

The black-throated toucanet was originally described in the genus Pteroglossus. Although not accepted by some authorities, the black-throated toucanet was split from the emerald toucanet to form a separate species.[3] While considered a species based primarily on morphology,[4] some authorities continue to consider it a subspecies of the emerald toucanet.[5][6] Alternate names for the black-throated toucanet include Andean toucanet and Peruvian toucanet.

Subspecies

Three subspecies are recognized:[7]

  • Black-billed toucanet (A. a. cyanolaemus) - Gould, 1866: Originally described as a separate species. Found in south-eastern Ecuador and northern Peru
  • A. a. dimidiatus - Ridgway, 1886: Originally described as a separate species. Found in eastern Peru to western Brazil and northern Bolivia
  • A. a. atrogularis - (Sturm, JHCF & Sturm, JW, 1841): Found on eastern slope of Andes from northern Peru to central Bolivia

Description

Like other toucans, the black-throated toucanet is brightly marked and has a large bill. The adult is 30–35 cm (12–14 in) long and weight can range from 118–230 g (4.2–8.1 oz).[8][9] The sexes are alike in appearance, although the female generally is smaller and slightly shorter-billed. It is, as other members of the genus Aulacorhynchus, mainly green. The vent and tail-tip are rufous. The bill is black with yellow to the upper mandible and a white band at the base of the bill. The throat is blue or black and the eye-ring is very dark, almost appearing blackish from a distance. The legs are dull greyish and the iris is dark.

gollark: They could also make a web frontend.
gollark: I assumed they would at least want emphasis or something.
