Great egret enjoys a slice of bread.

I was watching this great egret for a while at Kapok Park. There was still a handful of bread slices floating around the lake but the laughing gulls, grackles and cowbirds kept diving down for them. This egret watched for a while and finally took off flying across the small lake.  As he came closer to a slice, a cowbird seemed to try and stop him from getting it. He grabbed the slice anyway and flew over to the other side of the lake. He seemed to be enjoying his slice but how yummy can a soggy slice of stale bread be? I guess it's no different than eating bugs.
