smitty777 writes "A recent article in the Journal of Biogeography describes research showing that 15% of the snails devoured by birds on a Japanese island can survive the digestive process. This is thought to be the mechanism by which the snail populations can migrate from island to island, similar to the way plant seeds are deposited. From the article: 'In the lab, scientists fed the birds with the snails to find out whether any survived the digestive process. "We were surprised that a high rate, about 15 percent, of snails were still alive after passing through the gut of [the] birds," explained researcher Shinichiro Wada.'" As bad as riding in a bird's digestive tract sounds, I'd take it over flying standby on a puddle jumper.
