One of these things is not like the others. Lots of ring-billed gulls, a few Bonaparte's gulls and one Franklin's gull that was hard to miss. You an tell the Franklin is a new arrival because it still has the pink blush on its breast from its diet in South America. Gotta love winter gull migration.
