Scientists gathering stomach contents from a baby tiger shark.

Young tiger sharks and the cats that roam your neighborhood may have more in common than it appears. Despite living in environments that are obviously very different, both go for the kind of birds you’d expect to find in the suburbs, like sparrows, woodpeckers or doves.

That’s the counter-intuitive finding of new research published in the journal Ecology this week. Researchers caught young tiger sharks, pumped their stomachs and then released them back in the ocean unharmed, if a little hungry and confused.  The collected shark puke included a mess of feathers and some unidentifiable bird carcasses, which were sent off for DNA analysis that revealed the young sharks don’t even mess with the birds we normally associate with the sea.

“None of them were seagulls, pelicans, cormorants, or any kind of marine bird,” said the study’s lead author, Marcus Drymon of Mississippi State University. “They were all terrestrial birds.”

Drymon’s team wrestled over 100 three-foot-long juvenile tiger sharks on to a boat in the Gulf of Mexico to snatch their barf. A total of 41 out of 105 sharks had bird remains in their stomachs.

“Tiger sharks will see an easy meal and snatch it up, but I was surprised to learn that the sharks were eating songbirds–I assumed that they’d be seabirds,” says co-author Kevin Feldheim, a researcher at Chicago’s Field Museum who led the DNA analysis. “The tiger sharks scavenge on songbirds that have trouble flying over the ocean. During migration, they’re already worn out, and then they get tired or fall into the ocean during a storm.”

Feldheim adds that such wayward songbirds might also make for easier prey because they can’t handle themselves near water as well as seabirds like gulls could.

“In every instance, the timing of the tiger shark eating the bird coincided with the peak sighting for that species of bird off our coast,” says Drymon.

Tiger sharks live 15 years or more in the wild and eventually grow up to 14 feet in length. It’s unlikely adult sharks have to rely on backyard birds for their meals, but the new analysis and follow-up research could begin to shed more light on the challenges sharks and other species face in waters where industrialized fishing and other threats are on the rise.
