When I was taking these, there was also a guy with Canon 1DX-something and a huge lens, hand-held. He had an air of seriousness and was sometimes confidently bursting like a machine gun, the sound of which was super impressive but the bird was not moving. Oh well, many of the same pictures to quickly fill your dual memory cards, I thought.
(But then, to his credit, he might have been trying to capture the perfect "catchlight in the eye" moment or something all day. He was there before I and my wife arrived, we left for an hour for a nice walk and came back and he was still there.)
