Little tiny stones for their tiny little gizzards! I have uploaded photos of this place before, it’s always swarming with Rock Pigeons. Apparently, there is something special about these particular little stones?
I’ve never seen the flock this tight together though. I snapped two shots with the Nikon, but the 24/70mm lens wasn’t getting me in as close as I wanted to be so I hopped out and just waded into the flock.
Silly bird-brained birds!
