ABOARD US COAST GUARD HC-130 HERCULES—A U.S. Coast Guard airplane rumbled down an airstrip on Hawaii’s Big Island, carrying hundreds of pounds of rare and precious cargo: seven endangered Hawaiian monk seals.
Federal officials found most of the young animals malnourished late last year in the uninhabited Northwestern Hawaiian Islands, the northernmost islands and atolls in the Hawaiian Islands chain.
