I have heard the swans as they fly overhead - last week I was outside for a few minutes to get something out of my car, and when I looked up I saw a large flock of swans flying overhead. At first I thought they were geese, but they were white with longer necks, and they made a sound which was unlike geese.
This is the first time I have ever heard the swans as they migrate, although I have seen them in Aylmer and Long Point on several occasions.
