Both very interesting shots, definitely prefer No 1 but not to say No 2 isn't good. On that one though i would definitely reduce the saturation of the green on that background as it is over-saturated at the moment. Just reduce the green channel rather than the overall sats. That will help it to be less grainy as well. In fact, looking at it, I think you will find you'll get a better result if you leave the green channel and reduce the yellow first, then just adjust the green if necessary.
You've done an excellent job capturing them in flight so well done
Cheers,
