American White Pelicans tend to feed in groups, probably gaining an advantage of any fish their neighbor stirs up. This fellow swam away from the group into a spot where the fall colors from the tree line reflected in the shallow water. I believe the rougher water beyond the bird is deeper and has some flow as it heads into a canal.
His feeding style was more scooping along the water surface, and less plunging of his full head.
He seemed to be successful.
