Today I had a bit more luck with the Peregrines! As I walked up the footpath about 200m away from the nest, one of the adults flew past within the range of my 300mm. Although I would have preferred to have more warning and not be carrying a tripod at the time it was nice to see one in flight at a nice range. Also a buzzard at very close range. I need to experiment with different compositions for birds in flight. Does any one have any suggestions???
