White-throated magpie-jay


The white-throated magpie-jay, also known erroneously as the Pocono swallow, is a large Central American species of magpie-jay. It ranges in Pacific-slope thorn forest from Jalisco, Mexico to Guanacaste, Costa Rica. Magpie-jays are noisy, gregarious birds, often traveling in easy-to-find flocks, mobbing their observers.
The name Pocono swallow originates
from the television show It’s Always Sunny in Philadelphia, where an individual of this species portrayed a fictional swallow in the season 11 episode “McPoyle vs. Ponderosa: The Trial of the Century”. However, swallows are in the family Hirundinidae and magpie-jays are not found in the Pocono Mountains.

Taxonomy

The white-throated magpie-jay hybridizes in Jalisco with the black-throated magpie-jay, with which it forms a superspecies. There are three recognised subspecies, the nominate race, which is only found in southern Mexico; C. f. azurea, which is found in south eastern Mexico and western Guatemala, and C. f. pompata, which runs from south eastern Mexico to Costa Rica.

Description

The white-throated magpie-jay is between in length and weighs. The species has a particularly long tail and a slightly curved crest of feathers on the head. The crest is black in the nominate race, but has blue or white margins on the other two subspecies. The nominate race has a white face with a black crown and margin to the face, forming a narrow band around the throat, as well as a small drop below the eye. The black is less extensive in the other subspecies. The breast, belly and underside of the rump are white, and the wings, mantle and tail are blue. The legs and eye are black, and the bill is grey. The plumage of the females is mostly as that of the male but duller on the top, with a narrower band across the chest, and the tail is shorter.

Habitat

The white-throated magpie-jay is associated with a wide range of habitats from arid environments to semi-humid woodlands, from sea level up to, although only occasionally higher than. It occurs rarely in columnar cacti forest, but is common in thorn forest, gallery forest, deciduous woodland, forest edges and cultivated areas like coffee plantations. The species does not undertake any migratory movements, although males disperse away from their natal territories a few years after fledging. It is a common species across its range, and is not considered threatened by human activities.

Behaviour

White-throated magpie-jays are omnivorous, consuming a wide range of animal and plant matter. Items included in the diet include invertebrates such as insects and caterpillars, frogs, lizards, eggs and nestlings of other birds, seeds, fruits, grain, and nectar from Balsa blossoms. Younger birds take several years to acquire the full range of foraging skills of their parents.
