Green Jay - Cyanocorax yncas

The Green Jay is an unmistakable species that is relatively common in Mexico and elsewhere in Latin America, but was unknown in the United States until they started appearing in southern Texas in the 1970s.  They are still only found in the far southern part of Texas, but their range and numbers appear to be expanding in recent decades.  There is some debate as to whether there should actually be two different species of Green Jay.  Populations in the U.S., Mexico, and Central America are geographically separated from populations found in South America, and there are also differences in plumage and habits.

Habitat

Green Jays in the United States are most often found in dense forests along the Rio Grande river. In the rest of their range, they can be found in a variety of woodland habitats, typically in more open woodlands or along woodland edges and clearings.

Diet

Omnivorous, feeding on a wide variety of items, including insects and spiders, small lizards, snakes, and amphibians, small rodents, bird eggs and young nestlings, fruits, berries, nuts, and sometimes human refuse.

Behavior

Green Jays are often gregarious, foraging in flocks. They will use a variety of foraging techniques, depending upon locality and what food items are available. Very opportunistic.

Nesting

Green Jays have rather complicating nesting and breeding patterns. Typically, for birds in the U.S., a small breeding colony has one nest with one breeding pair of birds. The previous year's brood stays with the breeding parents and helps to defend the territory and raise the young. Nest building itself is also often communal, with multiple members of the flock helping to construct the nest, a crudely built cup of sticks, twigs, leaves, and soft plant material.

Song

Variable series of calls, often harsh croaking or other shrill calls.

Migration

Non-migratory, considered a permanent resident throughout their range.
