Howard Miller spent his childhood at his grandparents' hotel in St. Petersburg, rowing out to the small mangrove island just offshore to see the local birds.
The family sold the hotel, but still owned the island.
When the National Audubon Society, a non-profit bird conservation organization, approached Miller about taking control of the island as a bird sanctuary, the rest of the family immediately agreed.
"This island will be protected by the Audubon Society henceforth," said Ann Paul, a representative of the group. "We can look forward to having birds grow and raise their families on this island for generations."
