Gorgeous photo, great detail. There's no doubt about it, the D800 is an awesome instrument.
Bighorn sheep are amazingly beautiful animals. Just east of San Diego is the Anza Borrego State desert park where a subspecies of bighorn, the peninsular desert bighorn, live. These sheep are a little smaller than the mountain bighorn sheep and slightly grayer in color. There are approximately 220 head living within the park boundaries. Unfortunately the I-8 freeway has completely cut off this section of the herd from their traditional range with the bulk of the remaining population living in Baja California, Mexico. Nearly all the sheep in Anza Borrego are radio collared and numbered and each year on the weekend of July 4th, they conduct a 3 day sheep count. A herd this small risks being wiped out by a single virulent disease or any other problem that a genetic bottleneck like this presents. On the positive side, there are a lot of people dedicated to the preservation of this herd and their numbers are slowly growing.
