It has the world's largest coral atoll, its cleanest seas and healthiest coral reefs.

The bird has been living on the tiny coral atoll for the past two months, earning celebrity status among locals and tourists.

As a coral island (a raised coral atoll), it rises a mere 42 m above sea level.

They are sometimes locally abundant over coral atoll reefs or in lagoons, where they may be caught even in areas of severe wave action.

Over time however, the island eroded until it became submerged and a coral atoll was left behind.
