Introducing the Coal Tit from the new 2026 series "Polepole Kotori." Coal Tit is characterized by its white cheeks. The monotone coloring gives it a calm impression. The Porepore Kotori series includes four types: Japanese long-tailed tit, Japanese white-eye, Eurasian tree sparrow, and coal tit. These small, colorful birds are so cute and round that you'll want to line them up. These palm-sized birds make you feel like you can almost hear their high-pitched chirps.
