Other reviewers, who seem to be quite knowledgeable about birds, already posted what types of birds you may expect to find here. You can drive the 5 mile loop very slowly and stop at various look-outs and platforms. You can also take walks here. The refuge looks like a huge lake. You never quite know what you'll find here. Thousands of birds make their home at this refuge during the winter months. I always find it so impressive when a large flock takes off with this loud "whoosh" sound. Bring binoculars and your camera. I usually visit this refuge at least twice a year.
