Humans are not the only ones seeking shelter from the strong winds, heavy rains and deadly floods of Hurricane Irma.

Animals, too, are finding ways to stay safe — and often, they need human help.

The National Wildlife Federation says that some animals know how to take advantage of a hurricane’s aftermath: Raccoons scavenge for food in the tumult, and some bears use fallen trees for shelter.

But for most, the risks are severe. Fish can be electrocuted by fallen power lines. Migratory birds can be thrown off course. And animals that live in zoos, shelters and wildlife refuges are dependent on people who must decide which is less risky: waiting out the storm, or attempting a stressful, difficult relocation.
