Sparrows are joining the new 2026 series, "Polepore Kotori." Their cute, plump appearance brings to mind their hopping around. Also, pay attention to its diamond-shaped beak when viewed from the front! 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.
