This was my poor attempt at a bird shot in the mangrove forest pictured below. Thanks to Claude Gagnon and Chris Morton, I now know for sure that it's a snowy egret.

Iriomote Island is the most remote of the Yaeyama group, with 90 percent of the island covered by virgin subtropical forest, mangroves along the Urauchi River and several major waterfalls. It is home to the critically endangered Iriomote wildcat as well as about 2,000 people and has been called the “Galapagos of the Pacific” (or the Orient, the East, or Japan).
