Abstract
The Asiatic Dowitcher (Limnodromus semipalmatus) which breeds in Siberia is a rare species of Scolopacidae and has never been recorded in Japan. The author has, however, found one Asiatic Dowitcher on May 23rd., 1972 at the Lake Ogawara in Aomori Pref. and has been able to take photographs in color.
The details from this observation and the field identification comparing with the three species which might easily be confused, i. e. L. scolopaceus, Limosa limosa and L. lapponica, are given in this report.
