I grew up just south of St. Louis within walking distance of the Mississippi river. In the 50's, as kids we used to take hikes along the RR tracks that ran along the river. Never ever saw a bald eagle. In the late 70's, I was living in Dubuque, Iowa and one day while crossing the river I looked to the side and saw a bald eagle flying parallel to the bridge. First one I ever saw in my life. It was quite a thrill. Just a few years later we moved to Vancouver, BC and during the first Winter we were here, a friend told me to go see the bald eagles out a small stream about an hour East of the city. The wife and I went out on a Sunday morning and parked just over a small bridge and walked up along the stream. We saw a few bald eagles flying around and going around a bend in the stream we started really looking and counting. Then we noticed they were everywhere. We stopped counting at about 250. Quite a magnificant sight. About half way to Whistler, BC, where the Winter Olympics were held is a small town named Brackendale, every winter they do and eagle count in December or January and numbers are between 1 and 2 thousand. Truly amazing.
