I took this photo by surprise!
I was driving on my way to The Ice Fields Parkway, when I saw a nest precariously built on a girder type bridge. I noticed a teeny head poking out of the nest. When I looked around, I saw mom perched on a nearby tree. I slowly took out my camera gear and stated shooting. I managed to get this shot as mom flew around then began her descent to the nest. Look at the claws. Yikes!
