The island’s most prominent bit of history is the 1881 wreckage of the mail ship Acadia, which ran aground on the island when the lookout mistook the island for a cloud due to its white beaches. Ducie is a mere speck in the surrounding expanse of ocean, uninhabited except for the estimated 500,000 nesting seabirds that reside among the two plant species (Beach Heliotrope and at least one specimen of Pemphis) that grow over seventy percent of the island. Bird species that visitors may be able to see include Murphy's Petrels, White Terns, Great Frigate birds and Masked Boobies. Snorkelers love to visit the top of the wreck of the Acadia or in the atoll’s lagoon waters.
