Black-collared jay
The black-collared jay (Cyanolyca armillata) is a species of bird in the family Corvidae, the crows and jays. It is found in Colombia, Ecuador, and Venezuela.
The black-collared jay was originally described in 1845 as Cyanocorax armillatus. It and several other species were later moved to their current genus Cyanolyca. The black-collared jay and the turquoise jay (Cyanolyca turcosa) were for a time treated as subspecies of the white-collared jay (C. viridicyanus) but they were separated beginning in the 1950s.
The black-collared jay's further taxonomy is unsettled. The IOC, AviList, and the Clements taxonomy assign it these three subspecies:
However, BirdLife International's Handbook of the Birds of the World (HBW) treats quindiuna as a separate species, the Quindio jay, and retains the English name "black-collared jay" for the other two subspecies. Clements does recognize the taxon within the species as the "black-collared jay (Quindio)". At least one nineteenth centur author called the taxon Xanthura quindiuna.
This article follows the one-species, three-subspecies model.
The black-collared jay is 30 to 32 cm (12 to 13 in) long and weighs about 100 g (3.5 oz). The sexes have the same plumage. Adults of the nominate subspecies C. a. armillata have a violaceous-blue crown and nape. Their forehead, lores, and sides of the head are black. Their throat and middle of the upper breast are ultramarine with a thin black border that connects to the rear of the black face. Most of the rest of their plumage is cyan-blue. The inner edges of their primaries are dark brown and the undersides of their wings and tail are blackish. Subspecies C. a. meridana is slightly darker and more purplish blue than the nominate. C. a. quindiuna is larger than the nominate. Its crown and nape are darker (more similar to its back color) and its body, wings, and tail have a greenish tinge. Juveniles are duller than adults and have a grayer throat and more grayish body feathers that have blue only on their tips. All subspecies have a dark brown iris, a black bill, and black legs and feet.
The subspecies of the black-collared jay are found thus:
The black-collared jay inhabits the interior and edges of cloudforest, elfin forest, and mature secondary forest, especially in areas with much bamboo and tree ferns. In elevation it ranges between 1,600 and 3,200 m (5,200 and 10,500 ft) in Venezuela and Colombia and between 2,100 and 3,150 m (6,900 and 10,300 ft) in Ecuador.
