On Tuesday I was driving along highway 401 where it crosses the Grand river in south Kitchener when I saw the silhouette of a very large bird flying south of the highway.
I only saw it for a second or two before the view was cut off by the top of the windshield (and besides, I was driving), and saw it mostly in silhouette against dark clouds. Just before it slipped out of sight, though, I saw that it had a white head.
So I’m pretty sure it was a bald eagle, the first time I’ve seen one not in captivity. I was mildly surprised to see one so close to the city, but there have been other sightings elsewhere along the Grand river in the Kitchener area.
