Walt Staab took some incredible shots of a young Peregrine Falcon flying over the Celery Farm's Lake Appert just before the Hour on the Tower this morning.

Walt was nice enough to share them here.  Walt writes:

"It was harassed for a while by smaller birds, and it even frightened a duck enough for the duck to dive quickly to avoid attack [see below, top right photo]. The falcon rested for a bit in a tree then flew past the Pirie-Mayhood Tower, presenting me with some nice photos -- GREAT experience!"

BTW, they didn't used to call Peregrines "duck hawks" for nothing!

Entire sequence is below. 

(Thanks, Walt!)
