Getting Ready to Migrate

The Turkey Vulture or Cathartes aura is the most widespread of the New World Vultures. Every year these large birds migrate from central Arizona to Mexico for the Winter and then back again in the Spring. I took this picture just as the birds were beginning their annual migration. Most of them will be gone within two weeks or so. They do not fly but use the thermal air currents to glide most of the way.
