Last Friday I spotted a Double-crested Cormorant (Nannopterum auritum) in the waters off of Occoquan Bay National Wildlife Refuge. As I was bringing my camera up to my eye, the cormorant suddenly took off and I captured a couple of shots of the action. I was shooting almost directly into the light, so the bird is almost a silhouette, but I was happy to capture some of the action. As you may be able to see, the cormorant initially runs across the surface of the water to generate some momentum before it takes to the air.

When I went searching for the Latin name, I was a little surprised to see that it had changed. The Double-crested Cormorant used to be considered part of the genus Phalacrocorax, but, according to Wikipedia, a 2014 study supported reclassifying it and several other American cormorant species into the genus Nannopterum. The International Ornithologists’ Union reportedly adopted this change in 2021.
