Izu Leaf-warbler
Encyclopedia
The Izu Leaf-Warbler (also known as Ijima's Willow Warbler or Ijima's Warbler) is a species of Old World warbler
in the Phylloscopidae
family.
It is found in Japan
, the Philippines
, and Taiwan
.
Its natural habitat
s are subtropical or tropical dry forest
s, 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.
The Izu Leaf-Warbler is in practice hard to tell apart from the Eastern Crowned Willow 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.
