I understand what you mean and I will listen to them next time I find them. They like to hide out of sight. And some times they hide right on the ground so they blend in so well. The other day I was eating some cashews and a ground squirrel was watching me. At first he kept his distance then I talked to him and he came closer. I gave him a nut and he walked away and ate it. Then I looked over my shoulder and another one appeared so I gave him a cashew also. Then I looked over to my left and another one showed up. I gave them all some more cashews and we all sat there together looking off into the distance. It was a very interesting and peaceful moment. I knew that they did not fear me and they hung around for a half hour just sitting next to me.
