The first afternoon that we were in Las Vegas, we went down to the park to see if the Desert Bighorn Sheep were there. Here is some info on the park, http://www.birdandhike.com/Wildlife/Mamm/08Art/05_Bov/Ovis_can/Hemenway/_Ovi_hemen.htm Jim Boone and his website are the best information for finding wildlife in the Las Vegas area. He generously sent me emails with advice on where I could find my targets. There were about 20 in the park with one decent ram. It was cold in the low 30s. I shot about 100 images and we packed up to head to Hoover Dam.
About a 1/4 mile down the road I spotted 6 rams heading north toward a subdivision. I quickly wheeled around and headed back past the park to the subdivision on the other side. We found a dead end where we could look down on the wash below the park. I quickly spotted the rams and they had turned for the park. We quickly loaded up and headed back to the park. By the time I got my camera out at the park, the six rams entered the field. They singled out a ewe that giving off good chemical signals to the boys. They hung with her the whole time until I left.
