Hurricane Florence has captured people’s attention this week, and it’s a sure bet that this unusual weather is also being closely monitored by hundreds of millions of migrating birds.

This is the peak of the fall migration season, after all, and birds avoid bad weather — which is helping scientists predict migration patterns.

“Where it’s going to rain can have interesting impacts on birds. It can sort of outright just shut down migration,” explains Kyle Horton, a researcher at the Cornell Lab of Ornithology. “But right behind the storm can be really favorable conditions, so the migrants may take off as the storm sort of sweeps through.”
