Camera Critters - Double-Crested Cormorants

Double-crested cormorants are widely distributed across the United States and their population is growing thanks in large part to the discontinued use of DDT. This particular colony was nesting at the duck pond at the Denver Zoo. I counted 14 nests in just the top of this tree. The island in the middle of the pond had about six trees like this, the branches filled with the nesting birds. I have never seen so many birds in one place!

This cormorant just delivered some nesting material to his mate and flew off to get more.

Across the water, a small group of black-crowned night herons was roosting in the trees. I wondered if they got displaced by the nesting cormorants. There weren't any keepers around to ask.
