Sooty terns’ migration takes the birds into the path of hurricanes


Hurricane season has officially begun in the North Atlantic, and it’s not just coastal communities that have to worry. A population of sooty terns off the southwest tip of Florida might want to worry, too. Depending on when and where storms hit, the terns could be in for a tough time. Their migratory route overlaps with the general path of hurricanes traveling from the waters off Africa up to the United States, a new study finds.

Sooty terns can be found all over the world. But the ones that nest in the Dry Tortugas National Park, west of Key West, are among the best known. The birds have been the subject of a long-term study that started back in 1959, and of other studies that stretch back into the early 20th century. Those studies revealed much about the birds’ growth and behavior, but not much about the terns’ migration.
