You don't get too close before an alarm is sounded. They would make very good watch dogs!
In the lower center of the picture above, near the trail, is a brave Prairie Dog. He watched as I slowly walked forward, sounding the alarm with every movement I made.
I got to within about 10 feet of him and snapped this photo. The next step I took he disappeared into his hole in the ground.
I stood there for perhaps 10 minutes without moving when on the other side of the trail these two came out of their burrow. They watched me for a few minutes and must have decided that I was not going to do them any harm.
Still on the alert.
After a while, they ignored me, though I tried not to make any sudden movements to scare them away, I moved in a little closer.
And they obliged by posing for me, I swear they knew I was taking their picture!
They are so much fun to watch!
