You know that long 'kee-eeeee-arr' sound that a Bald Eagle's make in commercials?
Like this one ...
That sound that has become an almost iconic Bald Eagle sound ... isn't actually an Eagle. Bald Eagles have a weaker, whistling or thrilling call.
So if it isn't a Bald Eagle, just what are you hearing? It's a hawk of some kind, normally a Red-tailed Hawk.
