Green Jay

Early on 20 February 2014 we drove from Rockport south to Laguna Atascosa National Wildlife Refuge. Long-time readers of my blog will recall that, in 2012, it was here that Erika and I first found many of the birds that occur in the United States only along the Rio Grande valley.

Once again, we found our first Green Jays here. Seven races of Green Jay occur in North and Central America. Most of these subspecies intergrade where they overlap. South American Green Jays have a disjunct range and are distinctly colored, have different calls and behavior, are found in different habitat (mountains), and are, thus, potentially distinct species (Gayou 1995).

  1. Critical observations and documentations from this important overlapping range for the species you may see here as you describe, Dan. Can't imagine too much time devoted to it.
