This pair of White Ibis were feeding on my far right with a decent size flock. They were one of the first that came past like a parade. One or two at a time, then another…
To be clear, they were not the first ones. I missed those shots by a mile. After a bit I got the speed and focus right though. 😆

I hear you 🙂
My newer long lens worked great on these birds all day. My original Leica 100-400 was sharp and clear, but really hard design to use with in flight shots. The OM Systems worked much better.
