The white-throated toucanet (Aulacorhynchus albivitta) is a near-passerine bird found in the Andes from western Venezuela, through Colombia to northern Ecuador.

Taxonomy and systematics

Although not accepted by some authorities, the white-throated toucanet was split from the emerald toucanet to form a separate species.[2] The Santa Marta toucanet and the grey-throated toucanet were both formerly considered as a separate species (Aulacorhynchus lautus and Aulacorhynchus griseigularis respectively) until lumped as a subspecies of the white-throated toucanet in 2016.[3]

Subspecies

Four subspecies are recognized:[4]

Description

Like other toucans, the white-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).[5][6] 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. Some white-throated toucanets have a rufous patch near the base of the lower mandible. The throat of the Santa Marta toucanet is pale grey-blue and white or grey-blue in the other subspecies. The eye-ring is very dark, almost appearing blackish from a distance. The legs are dull greyish and the iris is dark.
