Mexican Jay - Aphelocoma wollweberii The Mexican Jay is found throughout much of Mexico, with a range that just crosses into the United States in southeastern Arizona, southwestern New Mexico, and southwestern Texas. Very social birds, Mexican Jays have complex social structures, particularly during the summer breeding season, when nesting groups cooperatively assist nesting parents in raising the young.  Even a single nest may contain eggs of mixed parentage.

Habitat: Found in open oak and mixed-oak woodlands, generally in canyons up to moderate elevations on mountain slopes.

Diet: Omnivorous, feeding on both plant and animal matter.  Feeds heavily on acorns and pine seeds when available, storing them in caches in the ground for later retrieval.  Also will feed on many insects in the summer, with other food items including small vertebrates such as small lizards or snakes, bird eggs, and fruits or berries.

Behavior: Complex social behavior during the breeding season, as discussed elsewhere on this page.  Uses a variety of foraging techniques depending upon food availability, foraging from the ground to relatively high in the canopy.

Nesting: The nest of a Mexican Jay is a large cup of twigs and sticks, lined with softer plant material, and placed anywhere from relatively close to the ground to 50 feet or more up in the canopy.  The female alone incubates the eggs, but while incubating, other individuals in the nesting group bringing food to the female. Both parents, as well as other members of the nesting group, help to feed the young.

Song: Has a variety of calls

Migration: Considered a permanent resident throughout their range, with little movement from breeding areas.
