Good effort on these, Jim. I agree that 200mm is not quite enough, usually. I often vacation in Orlando, (mid Feb this year is next) and one time I headed east to Merrit Island.

Lots of good photo ops of birds there. I was using a 70-200 f2.8 at the time, but I've added a 400mm since. Any other good spots near Orlando?
