Ijima's Leaf Warbler

Phylloscopus ijimae

Ijima's leaf warbler (Phylloscopus ijimae) (also known as Izu leaf warbler, Ijima's willow warbler or Ijima's warbler) is a species of Old World warbler in the family Phylloscopidae.

It is found in Japan, the Philippines, and Taiwan.

Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and subtropical or tropical moist shrubland.

It is threatened by habitat loss, but is locally abundant in steep and densely wooded areas whose topography makes habitat destruction for development difficult.

Ijima's leaf warbler is in practice hard to tell apart from the eastern crowned warbler, by physical appearance alone. It has the same dainty and perfectly proportioned features of the typical Phylloscopus warbler. However, the song - a series of quiet but fairly far-carrying squeaking sounds - is very different from the plaintive, Old World bunting like song of the eastern crowned.
