This afternoon we stopped at a park that is a desert oasis. There is a natural spring that feeds a large man-made pond. it's always good for wildlife, and there were quite a few ducks (Wigeon, Mallards and Ring-necked Ducks). Today we were watching a Cooper's Hawk chase a Gila Woodpecker overhead in mid-air. I have done a lot of birding over the years, and I have never witnesses such a spectacular chase scene. The hawk caught the woodpecker after a series of mid-air changes of direction.
