I have recounted this story here in the past, but it is a recent bizzaro memory from 2008...
Playing golf with a co-worker and family friend last year in the Cleveland area...par-4 hole, hit my approach shot just short and left of the green. Had about 40 yards to the pin on a raised green, and decided to hit a high floater with my 60-degree wedge.
As I hit my shot, a small group of swallows (at least I think that is what they were) comes flying across the green. These little birds had been all over the course, flying very quickly like bats about one foot above the surfaces over which they flew and also flying in circles. Anyways, these birds are "dancing" all over the putting surface and sure enough, my ball descends from the heavens straight down onto one of these speeding birds and...THUD!...pins it to the ground.
The bird laid there stunned, but began to flap one of its wings and it was breathing. I ran up there to see what had happened and lifted the bird up to go place it under a nearby tree for safety and to get it out of any further harms way. As we came back to the 18th hole (right near the same green) we went over to the tree and sure enough the bird had died.
I still feel so bad about the incident, but it was a completely harmless accident, one which I'd never seen happen before (and I hope never occurs again).
