I was headed to work last Friday and saw a slough absolutly covered with ducks. The slough is right by the highway and seldom has a lot of birds on it. As I got close to the water some of the birds got nervous and started to lift. As the first birds lifted I noticed a few woodies. I then realized that the whole body of water was covered with woodies. I had come upon a huge migration of these beautiful birds. I have never seen anything like this. They were feeding in barley field next to the water. Fun to watch.
