_Geographic range._--Breeds in northern Siberia. Ranges east to
Alaska and south to the Philippines and the China coast. In
Micronesia: Mariana Islands--Agrihan.
_Remarks._--The Herring Gull is ascribed to Micronesia on the basis of
one bird obtained by Marche in January, 1889, at Agrihan in the northern
Marianas and reported on by Oustalet (1896:56). The gull is considered a
straggler to the northern Marianas from the northward. Stott (1947:525)
observed a gull, which was thought to be this species or _Larus
ridibundus_, at Lake Susupe, Saipan, in 1945.
