The trumpeter swan pair in the Swan Corners ponds were chasing a goose out of "their" pond one day last week when my husband was going in to work from Clinton.

This is why the DNR would like to get rid of Mute Swans in Michigan, It is now agains the law to re-hab them, but that clearly isn’t enough. Many members of the public love these swans, o it’s going to be hard to eliminate them. i believe Trumpeter Swans have much better behavior toward other water birds.
