Crows and Osprey (I think)

I've learned that whenever I hear crows all excited about something, I should check it out. This morning I heard noises above me and saw these guys. I ran in to get my long lens camera so I could catch a bit of the fun. I'm pretty sure the big bird is an osprey. The small ones are crows of course, my buddies from way back. Though I'm really partial to osprey. Eventually the crows chased him off and my day continued.
