📍 Shinobazu Pond, Tokyo
Black-headed Gull (Chroicocephalus ridibundus)
A small, elegant gull recognized by its dark chocolate-brown breeding hood, red bill, and pinkish-red legs — this individual’s patchy hood marks the transition between winter and summer plumage.
One of Tokyo’s most familiar winter gulls, abundant at Shinobazu Pond in Ueno Park from October through April; the Japanese name ユリカモメ (yurikamome) even lends its name to the city’s waterfront rail line.
