The Brown Jay is a very large Jay species found mostly in Mexico and Central America. In the United States, their range just extends into southern Texas, where they are most often found in riparian forests along the Rio Grande river. There are a few scattered historical records of the species in South Texas, but they are considered more common residents in recent decades than they were historically.
Habitat
Found in a variety of forested habitats, particularly open forested habitats, forest edges, and in forest clearings. Not often found in dense unbroken forest. They will utilize second-growth and other highly disturbed forest areas.
Diet
Omnivorous, feeding on both plant and animal matter. Food items may include insects and spiders, other invertebrates, small rodents, small lizards and snakes, eggs, and recently hatched small birds. They also will feed on fruits, berries, nuts, seeds, and nectar from flowers.
Behavior
Uses a variety of foraging techniques, depending upon location and available food items. They are typically gregarious when foraging, moving about in small flocks.
Nesting
Brown Jays have a unusual nesting system, using a cooperative nesting system. Small flocks form, and each flock only produces one nest. Multiple females in the group may lay eggs in the single nest, which is a large cup built of sticks and twigs, placed in a tree. The females lay between 2 and 6 eggs, and females alone incubate the eggs. When the eggs hatch, the young are fed by all adults in the group. The young leave the nest after about 3 or 4 weeks.
Song
The most common call of a Brown Jay is a strong clear bugling note, often given in series. Flocks of Brown Jays are typically conspicuous and very vocal, calling frequently to each other.
Migration
Considered a permanent resident throughout its normal range.
