DNA analysis of shark barf tells scientists what kinds of birds the sharks scavenge

Tiger sharks have a reputation for being the `garbage cans of the sea`-they`ll eat just about anything, from dolphins and sea turtles to rubber tires. But before these top predators grow to their adult size of 15 feet, young tiger sharks have an even more unusual diet. Scientists have just announced in a new paper in Ecology that baby tiger sharks eat birds. And not seabirds like gulls or pelicans-familiar backyard birds like sparrows, woodpeckers, and doves.
