"From Death's Door, I Curse at Thee" said the goose.

This one has a bit more detail than the last one:

STOCKHOLM, Sweden - A Swedish hunter spent two days in bed after being knocked unconscious by a Canada goose that landed on his head moments after his son shot it dead, news reports said Wednesday.
The goose had been flying about 66 feet up in the air when it was shot by Carl Johan Ilback, who was hunting with his father, Ulf, along a stream in eastern Sweden in August.
When the goose dropped from the sky, it hit Ulf Ilback in the head and knocked him out, he said.
"It wanted to extract its revenge, I assume," Ulf Ilback told local newspaper Extra Ostergotland. "If it had gotten a better hit, it could have broken my neck."
Ilback spent two days in bed with severe headaches before returning to work.
"The story brought about a lot of laughter at work," he was quoted as saying, adding that during this month's moose hunt, he may wear a helmet.

I'm not sure that a helmet would help much, if a moose fell from the sky... but then, I suspect that flying moose would be protected by some kind of environmental law.
