Mr Peregrine In-Flight - Click image to view larger!

This is an outstanding shot, thinking at their speed on flight. What a beautiful bird!

Thanks Greg & Verena! You definitely shoot Peregrine before, LOL!  Fastest bird I've ever encountered. I've been shooting these birds for 5 months + now and ... not much to show for.  May be in a couple months I can post about 4,5 shots  :-)

Btw Greg & Verena! Notice that I took this with just the Canon 7D Mark II + 500mm F4 IS ... since even this setup is too shot to catch the Peregrine. Putting on the 1.4x  TC III will slow down the focus so much it's impossible to catch any flying shot of the Peregrine .  This bird is a 200mph + bird (or 300km +) ..
