Sharks with solid “hairballs” of migratory bird feathers found off Alabama coast


Tiger shark bellies found full of migrating birds; are Gulf oil and gas rigs to blame?, Press Register, December 31, 2010:

Feathers of woodland birds found in tiger shark bellies this fall bolster the theory that the Gulf’s offshore oil and gas platforms pose a fatal danger to migrating birds, according to scientists from the Dauphin Island Sea Lab.

“The best way I can describe what we found in the sharks is to think of a hairball like cats cough up,” said Marcus Drymon, a Sea Lab scientist who dissected several of the sharks. “The balls are just solid feathers and about as big around as a grapefruit. We caught these sharks during the fall migration in the general vicinity of the platforms off Alabama.” ...

“These are not gulls or pelicans. They are migratory birds that you would not typically find in a shark.”

Drymon said tiger sharks are the most likely candidate for eating birds that fall into the sea, as they are famous scavengers.
