I couldn't resist posting one more photo of the magnificent Peregrine Falcon I saw. I like this shot even better than the one I posted a couple days ago. This one made the bird more identifiable to me.
Here are a few fascinating things I learned about the Peregrine Falcon - "Their name comes from the Latin word peregrinus, which means "to wander." They are commonly referred to as the Duck Hawk. Peregrine falcons are the fastest-flying birds in the world – they are able to dive at 200 miles per hour."
