About three years ago I found a pair of Trumpeter Swans near me in Annapolis, MD. The trumpeter Swan Society said they were juveniles and wouldn’t mate for a while yet. They are generally monogamous and mate for life.
Last year it looked as though they were going to mate, but it didn’t happen .This year they started nest building in early April, and started incubating in late April. This can take over a month, and I found three cygnets this morning.
I’ve got a lot of photos and video, so I’ll just try to post the best of the lot.
