With the Niagara Gorge in the background, getting a lock on these speedsters is far from easy, and more then frustrating when tou miss!! always a challenge, and I can't wait to go back! I might go with a tighter crop if I print this.
It sure is frustrating when you see a great photo op but can't lock focus! Looks like you did a nice job here. Good eye contact, light, and sharpness. Wing position could be better. You guys are having a field day with the peregrines! Thanks for posting.
