My usual Saturday birding was cut short before I got any bird photos. Hopefully I can fit some compensatory birding in this week. In the mean time, here are a couple photos of a Round-Tailed Ground Squirrel chewing on its foot.
Feet are a good source of minerals and protein. The food pyramid recommends 3-5 servings of foot per day.
Some of the more gossipy Ground Squirrels are known for foot-in-mouth disease.
