Hi, we live on a cranberry bog reservoir that is quite marsh-like in new england. For the past 5 or so years the same swans have been returning each year. They typically stay for most of the winter as well. This year we had a really rough febuary with tons of snow. I haven't seen them since the storms started. Will they come back or is it possible they didnt make it. We have had a set of 3 swans here instead. I know its not the same ones because when I would whistle for the dogs the other 2 swans would come too.
