Thanks for your positive feedback friends
Akira, there was perseverance and fast reaction and even more anticipation involved. But I'd say equipment had its signifigcant share. Without the AF-Speed and fps of the D500 it would have been a lot more difficult to get these shots, I dont know how I would have ended with the D300/D700 combo I had used in former years. Long tele range also was not bad for not disturbing the birds.
