A Semipalmated Plover Charadrius semipalmatus was observed in Aisai City, Aichi Prefecture, on 17th and 28th November and 5th December, 2006. The obvious webbing between all front toes clearly distinguished it from the most similar species, the Ringed Plover C. hiaticula. Other features possessed by this individual that are more commonly present in the Semipalmated Plover than the Ringed Plover were: a narrow yellow orbital ring; a short, thick-based bill; at the base of the bill, the border between the dark coloration and white coloration below the eye reached above the gape of the bill. This is the first known record of the Semipalmated Plover in Japan.
