There are only a few spots on the Texas Gulf Coast were the Least Tern nest. We were lucky to find this colony and were careful not to disturb them from their routine.
Thanks for the constructive comments and questions.
Colin, this is actually a mature mating bird just a little beat up as this was the second mating of the year. The first time the birds mated/nested, we had abnormally high tides here on the coast. All of the nests that would normally be above the "high" water line were washed away. These terns where tired and very late in the season for nesting.
Bill, after reviewing this image, I like your suggestion, and in fact I am thinking of brightening the entire image slightly.
