Talk about hyperactive daycare … While out cruising with Captain Doug we found a double-crested cormorant rookery. A rookery is a collection of nests. There are at least four nests that you can see in the video. The parents were feeding their chicks. The parent carries a fish back to the nest within its neck pouch and allows its chick to poke its head into the parent’s throat and pull the fish out. Not the way I would want to feed a youngster but then I don’t have feathers and I’m not a cormorant. Jordan Lake.
