The black-throated toucanet (Aulacorhynchus atrogularis) or Peruvian toucanet is a near-passerine bird found in central Ecuador to western Bolivia.
Taxonomy and systematics
Although not accepted by some authorities, the black-throated toucanet was split from the emerald toucanet to form a separate species.[2] While considered a species based primarily on morphology,[3] some authorities continue to consider it a subspecies of the emerald toucanet, as Aulacorhynchus prasinus atrogularis.[4][5]
Subspecies
Three subspecies are recognized:[6]
- A. a. cyanolaemus - Gould, 1866: Found in south-eastern Ecuador and northern Peru
- A. a. dimidiatus - Ridgway, 1886: 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).[7][8] 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.
