Pigeons — How Can They Fly Off After I SMACKED Them? 
Only recently I have gotten into pesting (mainly feral pigeons) messing with the welfare of both cows and human beings.
Now, recently I've had some less than successful hunts —
and I'm hoping some of you can help me understand what is happening....
BACKGROUND
To the rats with wings at 35 and 45 yards the Skyhawk delivers the JSB 16's (15.89gr) with over 20 FPE.
With that rifle I normally can do sub-1.5" groups at 50y.
However, sometimes there is quite a bit of wind where I pest.
OBSERVATION
Recently, I've been having a lot of fly-offs — after I scored a hit, supposedly.
INTERPRETATIONS
(1) If I missed completley — there would be no smacking sound (but there is, and it's loud)....
(2) If I were only hitting feathers — there would be no smacking sound, but I'd expect feathers to fly (they often don't).
(3a) If I were hitting the body anywhere — at this speed I surely must have pass-throughs, and there should be feathers flying, I think....
(3b) Also, not that many pigeons should be able to fly away as if nothing happened, in controlled flight, a straight line, I think....
(4) I had it a few times that I hit one, I heard the smack, and the pigeon fell straight down.
But when I later went to retrieve it, it was nowhere to be found.
What is going on...?!?
Thanks for giving me some interpretations of what might be happening.
(And yes, I know, if I hit their head every time, this wouldn't be happening.)
