Canada Geese flying North for the Summer

I think one of the most spectacular sights in nature is watching a flock of Canadian Geese as they fly in their infamous "V" formation. I recorded this on March 17, 2012 a ~2:00 PM EDT as a small flock with some 35-50 birds flew from West to East about 2 Km North of our house. This was one of the smaller flocks, but I've seen "V" formations with 100's of birds, it's quite a sight. My house happens to be on one of their routes here in the Montreal region. Here is the sound they make flying over. The picture is one I took two years ago now near a provincial park very close to my house. This was a couple I think that were nesting in a swampy area of the park.
