  • Forages together in family flocks that rove woodlands and thickets, searching all levels of the vegetation for insects, fruit, and small vertebrates, maintaining contact with noisy calls. Highly social and territorial year-round, driving away rival Green Jays and mobbing predators such as owls or snakes.

  • Woodlands, thickets, and parks, especially sites with native trees, but also citrus orchards and parks.

Regional Differences

Seven fairly similar subspecies range from Texas (glaucescens) to Honduras (centralis). Another very different and geographically isolated set of subspecies inhabits northern South America. These differ in having tufted forecrowns and bright yellow bellies. The South American subspecies are collectively sometimes called the Inca Jay.
