Herring Gulls are large birds, not shy of humans, and easy to photograph. I saw the ones below on the shore of Chincoteague Bay on Assateague Island in Maryland. The younger ones were flying back and forth, while two adults stood and rested not far from where I was.
Ponds and lakes in our area are frozen and mostly covered with ice. I went and walked around some of them and saw a few hardy birds. Flocks of dunlins were flying around, landing and taking off near any open water spot.
This herring gull was or had just finished eating a mussel, I believe.
Other gulls were half asleep in broad daylight, maybe trying to conserve their body heat.
Only one juvenile Herring Gull was doing aerial acrobatics for my camera.
