Purplish-backed Jay

Overview

The purplish-backed jay is a striking member of the crow family, distinguished by its purple and black plumage. It is endemic to northwestern Mexico, where it inhabits dry deciduous forests. Although its population is gradually declining due to habitat degradation, the species is currently assessed as being of least concern.

Identification

• Cyanocorax beecheii is a medium-sized bird ranging from 35 to 41 cm in length, with males generally larger than females.
• Plumage features a purplish-blue back, wings, and tail, with the lower mantle and rump displaying the brightest hues.
• The head, neck, upper mantle, and underparts are black, including the underside of the wings and tail.
• Distinctive features include a small ruffled erectile crest on the forehead, a powerful black bill, and yellow irises and legs.

Habitat

This species is restricted to northwestern Mexico, where it primarily resides in dry deciduous forests. It is an omnivorous bird that occasionally leaves the forest to feed in orchards, grain fields, rubbish dumps, and along road verges.

Diet

Feeding on invertebrates and small vertebrates, the jay employs varied foraging strategies, including catching insects in midair, plucking them from leaves, and probing bark for grubs. It also forages through plant litter and may visit human-modified environments such as orchards and grain fields.

Did you know?

Members of a social group assist the female in building an untidy platform of twigs, and the dominant pair's chicks are fed not only by their parents but also by other members of the group. Juvenile males typically remain with the group for a year or so before dispersing, whereas females may stay indefinitely.
