Through searching the internet I learned that the endangered Whooping Cranes are frequently sighted along Joe Overstreet Rd. Upon arriving at the boat launching/camping area on my first visit I noticed a gentleman with a Canon 500mm L lens set up on a tripod pointing towards an area of trees with cattle and cattle feeders underneath.
He kindly pointed out that he was photographing the Whooping Cranes that were mixed in the Sandhill Cranes around the feeders. Although the distance was quite far for my 100-400 I was still able to capture a decent image of the large white bird. The smaller gray cranes in this photograph are the Sandhills.
During my stay the Whooping Cranes would fly into this feeding area each morning after sunrise and could be viewed most any time of day feeding around the cattle feeders.
