Early last week I thought that the Pronghorn bucks on Antelope Island State Park might be in rut, later in the week a buck’s behavior confirmed that they are. For the next few weeks it ought to be more fun than usual photographing them.

There were several does in the harem…

Plus a few young Pronghorn…

And this buck who kept a close eye on his harem.

The fawns born this spring have sure grown a lot yet they are still pretty darn cute.

Pronghorn bucks expend a lot of energy during the rut keeping the does in his harem close to him and by fending off the other males.

When one of the does or fawns breaks loose from the harem the buck will chase after them to get them back into the herd.

I think it is awesome to watch the powerful muscles of Pronghorn as they run, they are the fastest land mammal in North America.

When this buck’s harem ran across the road he followed them close on their heels.

My mother’s visit went great, she saw many lifer birds and wild animals, she loved seeing Utah and spending time with me. I hated to see her leave.

I’ll be slowly catching up on viewing your blogs and images and replying to the wonderful comments you have left here while I was enjoying her company.

Life is good.
