DISTRIBUTION
Range.—Eastern Siberia, south in winter to southern China and India; casual in Alaska.
Breeding range.—The spoonbilled sandpiper has been found breeding only along the Arctic coast of northeast Siberia (Cape Wankarem, Pithkaj, Cape Serdze, near Koliuchin Island, and Providence Bay).
Winter range.—The winter range of this species appears to be mainly on the coasts of India (Rangoon, Akyab, Tenasserim, and the Arakan coast).
Migration.—Specimens have been collected at Shanghai, China, in April and it seems to arrive on its breeding grounds early in June (Emma Harbor, Siberia, June 6). An early date of fall arrival is indicated by a specimen from the mouth of the Amur River, southwestern Russia, taken on August 8, while a late date of fall departure is October 8, at Hakodadi, Japan.
Casual records.—A specimen of this sandpiper has been reported as taken on the Choris Peninsula, Alaska, in 1849 (Harting, 1871), but subsequent investigation (Dixon, 1918) indicates that the bird was probably taken on the Siberian side of Bering Strait. Two specimens were, however, taken near Wainwright Inlet, on August 15, 1914 (Dixon, 1918).
Egg dates.—Siberia: 2 records, June 22 and July 15.
