Tiger sharks (Galeocerdo cuvier) are known as the ‘garbage cans of the sea’ because of their diverse diet that includes actual animals (like fish and sea turtles) to… well, garbage (like chicken wire and rubber tires). And while it isn’t new news that tiger sharks eat seabirds, scientists have discovered that baby tiger sharks are feeding on birds one normally finds in their backyard like sparrows, woodpeckers, and doves!

Measuring up to 14 feet (4.2 m) in length and capable of weighing 1,400 pounds (635 kg), they are a migratory shark found throughout the world’s tropical and warm temperate oceans. Assessed by the International Union for Conservation of Nature (IUCN) as Near Threatened, adult tiger sharks are known to feast on one of the bigger birds to take flight in our skies: the albatross. Off the coast of Hawaii, young Laysan albatrosses test their wings as they learn the art of flying, often landing in the water and the awaiting jaws of this predator. The French Frigate Shoals are famous for this display, but it was previously unknown that the young eat birds let along such a unusual type of avian.

Marcus Drymon of Mississippi State University is the lead author of the new paper in the journal Ecology; his team brought 105 tiger sharks aboard their boat in the Gulf of Mexico, pumped the stomachs of these young sharks, and then released them back into the wild. Kevin Feldheim, a researcher at Chicago’s Field Museum and a co-author of the new study, was one of the scientists who helped analyze baby tiger shark stomach contents to see what birds the sharks were eating.  Of the 105 sharks studied, 41 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 songbirdsI assumed that they’d be seabirds,” said Feldheim to Science Daily. Reiterated Drymon: “None of them were seagulls, pelicans, cormorants, or any kind of marine bird.”

Since the remains of the birds were often already a little bit digested, the scientists were not able to ID them right off the bat. So the scientists sent the samples the Field Museum’s Pritzker Laboratory for Molecular Systematics and Evolution for DNA analysis to see if anything could be identified. Breaking down the vomited remains to their basic molecular components, the scientists examined the DNA sequence results and then compared them to a bird DNA database to see just what was in the young shark stomachs.

But where did the songbirds come from? Surely they weren’t just flying in the middle of the ocean… right? Not necessarily. Drymon’s team was in the Gulf of Mexico, a unique semi-enclosed sea on the southeastern periphery of the North American continent. From the Yucatan to the Florida peninsulas, it borders five of the United States, Cuba, and the eastern part of Mexico. In fact, sometimes it is called “America’s Sea.” It covers more than 600,000 miles2 (almost 1.5 million km2), in some areas is as deep as 12,000 feet (3,660 m), and receives freshwater from over 30 major river systems, creeks, and streams. Above her water, the Gulf of Mexico allows millions of songbirds to use her skies to migrate between the USA and Mexico. “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,” explained Drymon.

Each year millions of land birds migrate across or near to the coast of the Gulf of Mexico, in a hemispheric-scale phenomenon known as the Nearctic-Neotropical bird migration system. A new study published in the journal Global Change Biology combined data from citizen scientists and weather radar stations and found that an average of 2.1 billion birds migrate over Gulf Coast. “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,” adds Feldheim. Yup, you read that right. The sharks are eating birds that fall out of the sky. Not only is their exhaustion already an advantage for the young tiger sharks, but so is their surroundings. The terrestrial songbirds probably aren’t as strong in the ocean compared to the seabirds who call it home. Scientifically speaking, ‘songbirds’ are part of the Passeriformes family, known for how they perch and their complex voice boxes. This includes about 4,000 species – about half of the world’s overall birdsup to 55 families.

Feldheim argues that the study shows the importance of having DNA databases available to scientists: “It shows us how much more we can still learn about sharks in general and what DNA can tell us that observation can’t.” This means businesses like Otlet are especially important moving forward. Founded in 2017, Otlet is a biological sharing database where scientists can submit a record of their shareable research samples, search ones available from other teams, and request samples from one another. And just how Otlet is a global collaboration, this study was also an effort of multiple scientists from the Mississippi State University Extension Service, Mississippi-Alabama Sea Grant, Field Museum, Forbes Biological Station-Bellrose Waterfowl Research Center, the National Oceanic and Atmospheric Administration National Marine Fisheries Service, and the University of South Alabama.

In short, the ‘Baby Shark’ song just got a new version—all about what they eat. Doo doo doo doo doo doo.

However where did the songbirds originate from? Undoubtedly they weren’t simply flying in the middle of the ocean … right? Not always. Drymon’s group remained in the Gulf of Mexico, a distinct semi-enclosed sea on the southeastern periphery of the North American continent. From the Yucatan to the Florida peninsulas, it surrounds 5 of the United States, Cuba, and the eastern part of Mexico. In truth, often it is called “America’s Sea.” It covers more than 600,000 miles 2(practically 1.5 million km 2), in some locations is as deep as 12,000 feet (3,660 m), and gets freshwater from over 30 significant river systems, creeks, and streams.

The sharks are consuming birds that fall out of the sky. Not just is their fatigue currently a benefit for the young tiger sharks, however so is their environments. The terrestrial songbirds most likely aren’t as strong in the ocean compared to the seabirds who call it house.
