Anas clypeata Mayr, Birds Southwest Pacific, 1945, p. 302 (Micronesia).
Geographic range.—Breeds in northern Europe, Asia, North America and adjacent islands. Winters to northern Africa, southern Asia, Philippines, Hawaiians, southern United States to Central America. In Micronesia: Mariana Islands—Pagan, Tinian; Caroline Islands—Ponapé, Pingelap.
Specimens examined.—One female from Mariana Islands, USNM—Tinian (Oct. 12).
Remarks.—The Shoveller is known from localities in the Marianas and in the Carolines. In the collections of the American Museum of Natural History there is a female taken by Rollo Beck at Kauehi, Tuamotu Archipelago, on March 6, 1923. A specimen examined from Tinian was taken there by Joe T. Marshall, Jr., at Lake Hogoya on October 12, 1945. Richards obtained two Shovellers (one immature male and one immature female) at Ponapé on December 21, 1947, and January 6, 1948, respectively. He found them in a pond in a bomb crater. This duck appears to be a casual winter visitor to Micronesia and other parts of Oceania.
