Ijima's Leaf-warbler Phylloscopus ijimae

This small warbler has a very small population that only breeds on a few small islands off the coast of Japan. In winter they migrate across to some areas of mainland Japan and south to Taiwan and the northern Philippines. As their breeding grounds are so restricted, this species is vulnerable to any predation or disturbance to those few, small islands.
