Peregrine Falcon - Juvenile eating fledgling Common Tern

I'd just started onto the sand when an early morning beachgoer told me there was a hawk eating something on the ground a few hundred yards ahead. It wasn't two minutes before I encountered this bird, and I scrambled to get my rig out of my backpack, assemble it, and close the 100-yard distance between the subject and me. Using a combination of walking and crawling, I maneuvered to within 20 yards of the bird just as the sun cracked the dunes behind me. The pinkish rays illuminated the scene perfectly, and I was able to crack off a few frames before the falcon was pushed off by a pair of mobbing terns. Had the terns arrive a minute earlier or the sun a minute later, this shot would not have been possible. You can see the sun peeking over the dunes in the reflection in the bird's eye!
