After a trip to the store today, I went by Kirk Pond to see if the White Pelicans were there. Sure enough they were. They have been there every day that I checked by the last couple weeks. Much of the time, they are tightly grouped and in unison bobbing their heads under water feeding. After watching a while, I concluded they do that as a group to sort of herd the fish into a group that they can then catch. Alas, the feeding group has been too far away to get a good shot of, so for today I photographed a beautiful white pelican and a cormorant sharing the pond.
I learned that it isn't strange for pelicans and cormorants to be seen together. Notice this "Cool Fact" from All About Birds https://www.allaboutbirds.org/guide/American_White_Pelican/overview ):
"American White Pelicans and Double-crested Cormorants are often found together. They sometimes forage together (though they mainly hunt different fish and at different depths). Cormorants even nest individually or in groups within pelican colonies."
