I don't think there's a more exciting site than a flock of birds flying in some sort of formation. This small group of Curlews made a good study.
The hope is if you take enough one will turn out to be the perfect balance in shapes and positions. I haven't managed it yet but at least you don't have loads of slides to throw away!
No excuses for going back to Lapwings. I think that they are a great subject, and many painters have felt the same judging by the number of pictures you see of them. Estimate how many above in a couple of seconds with out counting.
This lot were just about getting their formation flying sorted out. Sadly I never did see what had put everything up, may be just a Heron or Harrier, but I may have missed something much better.
Even the Black-headed Gulls had a go at a square formation, but the bottom one got its timing wrong.
