These three white pelicans seem to have staked out our wall for their feeding area this week. I'm not sure what the single brown pelican is doing hanging with these white ones. It could be that this brown one cannot see to dive for his food and is depending on these white ones to locate the food and will then share in the bounty. Brown pelicans often die of starvation since their preferred method of diving for food leads to blindness from the impacts with the water.  The white pelicans feed by cooperating with each other to herd the bait into a small area and then launching their attach from the water instead of from the air.
