I was sitting on a stone at the water's edge of this steep slope and tried to get low, when this bird flew so close that
I could barely fit it into the frame. (Full frame plus added some canvas to the top and right)
I wished for the 300 f 2.8 that I no longer have.
Fortunately the active focusing point was set to the very top which helped. (was sitting on the neck)
Thanks for looking.
