We have many Fox squirrels in our yard. They are fun to watch. I used to get upset when they raided my bird feeders, but since I switched to safflower seed they are no longer interested. I don't even mind that they moved into the wood duck box I put up in the dying Ash tree by the river.
I photographed the one above in February of 2011, basking in the sun on the back of our patio furniture.
This morning I noticed one on the patio steps. He was busy with something up and down the junction of the sandstone steps. He would pause periodically and chew. There is moss there, but I've never seen a squirrel eating it in any of the other many locations around the patio.
Does anyone know what is behind this squirrelly behavior?
