What a spectacular day for a walk. The air was warm and the earth was alive with birds and animals preparing for winter. Migrating sparrows, cute little chipmunks and coyotes posed for some portraits. I was trying to get close to some sparrows that I had not seen before and in the process flushed out two urban coyotes from willow bushes around a slough on the University research field. One took off on a determined trot while the other was quite content to pose for some photographs.  The sparrows turned out to be American Tree Sparrows, a species that I have never identified before so I was happy to get some good images.
