About the Japanese Leaf Warbler

The Japanese leaf warbler (Phylloscopus xanthodryas) is a leaf warbler (family Phylloscopidae). The species was first described by Robert Swinhoe in 1863. It was formerly included in the "Old World warbler" assemblage. It is closely related to the Arctic warbler and the Kamchatka leaf warbler, to which it was formerly considered conspecific.

It is found throughout Japan, except on Hokkaido; it winters to Southeast Asia. The Japanese Leaf-Warbler is sized between 12–13 cm in length. They typically have darker green upper body feathers, with an under body (or belly) with lighter green feathers. They have a very short and black (with a hint of yellow) beak, as well as extremely small legs that vary from pale yellow to orange-brown. The bird has a clear yellowish-white eyebrow stripe above the bird's dark eyes. Adults are bright olive-green (with a white wingbar and greenish tail). Both sexes look alike. Juveniles are roughly similar, yet duller in color (more grey-brown).
