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.
Similar Species: Not likely to be confused with
another species if seen well.
Conservation Status: Populations are large, appear
to be stable or increasing, and are found over a relatively wide geographic
area. The
IUCN lists the Brown Jay as a species of "Least Concern".
