Gigrin, great place to be, I love the Rhayader area.
Anyway, 2 lovely shots, sharp with some nice detail in strong lighting. I think you have enough space in the first image to crop the band of what looks like dead grasses and that will lose you the 2 crows as well, making for a cleaner image with more emphasis on the buzzards. The 1st image would then be my pick of the 2.
I wonder if it's the same 2 I got a couple of years ago, they were going at it as well.
