Hello, everyone! Have you ever heard of the White’s Thrush, known as “Toratsugumi” in Japanese? If you’ve ever been in a forest at night and heard a lonely “Hyo, hyo” sound echoing through the trees, that was likely the call of the White’s Thrush. This bird lives in mountainous areas across Japan, staying mostly hidden during the day but making its presence known at night. Its distinctive call has left a lasting impression on many people over the years, sometimes even inspiring fear.
The White’s Thrush is about 30 cm long, roughly the same size as a Brown-eared Bulbul. Its body is yellowish-brown with black spots, and its underbelly is whitish, while its legs are a pale reddish color. In the forest, its coloration acts as camouflage, making it quite difficult to spot. So if you happen to come across one, consider yourself lucky!
In Japan, the White’s Thrush is known as a resident bird or a partial migrant. During the summer, some migrate to Hokkaido, and in winter, they may fly to warmer regions. You might also spot them in broad-leaved forests in hilly or low mountainous areas, or even in wooded parks. In winter, you might see them on the ground, moving leaves aside with their bodies in search of worms, with a distinctive up-and-down movement of their hips.
But what truly sets this bird apart is its voice. Particularly from midnight to early morning, it emits a haunting “Hyo, hyo” sound, which is both melancholic and a bit eerie, reminiscent of a flute. Sometimes, you’ll hear them calling even during the day if it’s rainy or cloudy. In ancient times, people found this sound unsettling, leading them to associate it with the legendary monster “Nue.” The White’s Thrush has left its mark on many pieces of Japanese literature as well.
Its unique voice has been remembered by many over the years. So, if you’re ever in a forest at night and hear that “Hyo, hyo” sound, it might be a sign that a White’s Thrush is nearby. This mysterious yet captivating bird might offer you a new discovery if you keep an ear out for it. Until next time!
