Max Gotz was curious about hazards of golf balls to birds.

At Midway Atoll, a nine-hole course can't help but run through the
albatross colony, because Laysan Albatrosses nest virtually everywhere.
My golfing partner one day sliced a shot that caught an albatross in the
side of the head from about 10 feet away. That became one dizzy
albatross--probably didn't survive very long.
The most interesting thing I observed with golf balls at Midway was
rolling a ball across a green and having a Bristle-thighed Curlew chase it
down. I assume the ball's similarity to an egg caused the response, as the
curlews do a little egg predation out there.
Midway's ultimate hazards were the petrel colonies--let your ball get in
there and down a burrow it goes.
