Wednesday in Wyoming -- May 10, 2017

What are this pair of hawks doing?  Dining!  At first the younger one appeared content to watch its parent, but soon the lure of fresh meat took over.

As you can see, there was a bit of a struggle.  You can guess who won.

The next morning, the youngster returned to the same site, as if expecting food to have been delivered there.  It wasn't.

I believe these are Swainson's hawks, which are common here, but I'm not 100% certain.  Can you confirm that?
