_Geographic range._--Breeds in Iceland, Europe, northern Asia. Winters in Europe, Africa, Asia, Malaysia, and parts of Oceana. In Micronesia: Mariana Islands--Pagan, Saipan, Tinian, Guam; Palau--exact locality unknown; Caroline Islands--Yap. _Remarks._--The Tufted Duck is a winter migrant to western Micronesia. It has been recorded only a few times and may be an irregular visitor. Flavin observed a duck, which he thought to be of this species, at Guam on January 19, 1946. Marshall (1949:221) reports that two Tufted Ducks were seen at Lake Hagoi in April 1945. =Aythya valisineria= (Wilson) Canvasback _Anas valisineria_ Wilson, Amer. Ornith., 8, 1814, p. 103, pl. 70, f. 5. (Type locality, Eastern United States.) _Nyroca valilisineria_ Reichenow, Ornith. Monatsber., 1901, p. 17 (Jaluit); Schnee, Ornith. Monatsber., 1901, p. 131 (Marshalls); _idem_, Zool. Jahrbücher, 20, 1904, p. 390 (Marschall Inseln). _Nyroca valisineria_ Phillips, Nat. Hist. Ducks, 3, 1923, p. 124 (Marshall Islands). _Aythya valisineria_ Hand-list Japanese Birds, 3d ed., 1942, p. 207 (Marshall Islands). _Geographic range._--Breeds in northwestern and northcentral North America. Winters south to Gulf States, Florida and Mexico. In Micronesia: Marshall Islands--Jaluit. _Remarks._--Reichenow (1901:17) and Schnee (1901:131) reported three species of American ducks (_Aythya valisineria_, _Anas acuta tzitzihoa_ and _Anas crecca carolinensis_) in the Marshalls in October, 1899, and May, 1900. These species may be stragglers to eastern Micronesia. =Accipiter soloënsis= (Horsfield) Chinese Goshawk _Falco Soloënsis_ Horsfield, Trans. Linn. Soc. London, 13, 1821, p. 137. (Type locality, Java.) _Accipiter soloënsis_ Hand-list Japanese Birds, rev., 1932, p. 182 (Yap); Hand-list Japanese Birds, 3d ed., 1942, p. 203 (Yap, Rota); Mayr, Birds Southwest Pacific, 1945, p. 302 (Yap). _Geographic range._--Breeds in northern China south to Kwangtung. Winters to Malaysia. In Micronesia: Mariana Islands--Rota; Caroline Islands--Yap. _Remarks._--The Chinese Goshawk is a winter visitor to Micronesia and has been recorded at Rota and Yap. The NAMRU2 party saw several unidentified hawks in Micronesia in 1945. At Mt. Tenjo, Guam, Muennink saw a small hawk, resembling an accipiter, darting at swiftlets on June 8, 1945. At Angaur, the writer saw a small hawk flying through heavy vegetation along the rugged coast line on September 21, 1945. A hawk "_Butio_(?)" was reported at Saipan in 1945 by Moran (1946:262); this hawk may have been _Butastur indicus_ (Gmelin). Marshall (1949:221) reports seeing "three kinds of hawks" on Palau in November, 1945. Obviously, further observations and collecting will increase our knowledge of the known number of kinds of hawks which visit Micronesia. =Accipiter virgatus gularis= (Temminck and Schlegel) Asiatic Sparrow Hawk
