Cool shot!

Nice timing! What species (of bird) is that?

If you took a RAW format version of that, did you try recovering the over-exposed white, in a histogram or levels tool? You can’t work miracles, but if the white is only a little over-exposed you might get somewhere.

Over-exposing white birds (is this an egret?) is of course something that just happens unless you know a few minutes in advance your next subject is white! Better to get the action shot than no shot at all. But if your lens has a ring set up for exposure compensation, do use it if you get the chance.

Stronger blur removal in a third party tool might also help (e.g. Topaz AI) - but is very hit and miss.
