Land Birds as Shark Prey.

A new long-term observational study found that tiger sharks in the north central Gulf of Mex ico have consumed at least eleven species of birds since 2010 - but the sharks were eating terrestrial birds, not marine birds. From 2010 to 2018, as part of a shark monitoring program off the coasts of Mississippi and Alabama, researchers led by biologist Marcus Drymon of Mississippi State University sampled the stomach contents of 105 tiger sharks. Using bird observation data from the online citizen science database eBird, they found that the date of each bird-shark interaction occurred at or near the peak of that bird species' migration through the area.
