It is one of Japan's three songbirds, and is also called the "haruen-dori" because of its call "Hohokekyo".
It is the size of a sparrow, with a faded olive back and white belly. The base of the legs is a light flesh color. Its facial features include a yellow beak and white eyebrows. When it chirps, it stretches its neck to make its voice echo.
I can hear it very often, but I can't quite see it. Hence the English name "Bush Warbler".
Everyone must have heard the warbler's cry called "Hohokekyo" in spring. The day when the warbler chirps are heard for the first time in the year is called the "first chirping day" and is used for phenological observation along with cherry blossoms and swallows.
In addition to this characteristic song, the warbler also makes a call called ''valley crossing,'' which repeats ''kekyokekyokekyokekyo
