Thank you..

As to age, I am sure there is, but I am not aware of it..don't think its like the rings mountain goats or sheep get as these guys shed the outside every year...so by mid-November is hard to tell the bucks from the doe's other than the bucks have a black face typically...

Pronghorn are unique as they are the last of their kind..they are not related to any other species that I am aware of....they are the fastest animal in N America..something like around 55 to 60 mph..incredible eye sight and great hearing...they are one of my favorite animals to hunt, rifle or bow...
