Dead birds?

We've been trying to figure out why there are a strange number of dead birds on the sidewalk between our house and the beach. We asked the lovely cashier at the grocery store and she said she didn't know. Then she went on to tell us a story about a nearby beach, that she and her husband think is so picturesque, except that one time they were walking along and saw a horse's head. No horse, just a head. Then they went to a different beach (with their 3 year old triplets) and realized they were at an all male nude beach. Ohhh Australia.
