Now, that is funny! From the gull or from the gull's well-aimed dropping? (Gulls are known for that kind of thing)
I'm surprised that the movement is so frozen at 1/750th. Did you catch this one on a glide?
Gulls have a very slow wing beat, glide a lot, and it is therefore much simpler to stop their wing motion. I've done it even with my c8080 at 1/250, but of course I got nowhere the detail that NHL has gotten.
