A sequence of photos taken on the Lake Huron shoreline in the spring.
I was photographing a Common Tern on a rock in the water when a second bird flew in.
The second bird landed and approached the one on the rock. By the front birds wing position it was fairly obvious what was going to happen next.
The birds mate. I’m guessing that they were a well established pair as the male didn’t bring a fish as a courtship offering.
After mating both birds started preening.
