A colorful tropical bird found primarily in Mexico and South America, the Green Jay just makes its way into the United States in southern Texas.

Cool Facts

  • The Central American and South American populations of the Green Jay are separated by 1,500 km (900 mi). The two different groups differ in color, calls, and habitat use, and may be different species. The South American Green Jays are larger and have a crest in front of their eyes.
  • A Texas Green Jay flock consists of a breeding pair, the current year's nestlings, and one-year-old, non-breeding jays from the previous year's nest. The one-year-olds defend the territory, which aids the parents, but they are ejected from the family flock soon after the current year's nestlings have fledged.

  • In Colombia, the Green Jay retains offspring for several years, and those young help the parents raise more chicks.
