During an evening walk on the Serpentine River in Surrey, BC, a trio of male Common Mergansers were fishing in the same general area. Spread out, each bird would dive with his own timing and rhythm along the ribbon of water and pop up twenty yards from where he had started. As if some quick discussion took place, the three birds started moving towards each other, all headed in the same direction, This still was the photo finish for an unspoken and lazy race, from which, they all headed off once again to fish their own corners of the river.
