HYruTHETICAL LIST. 757 



Wisconsin, even in the southern part of the state, but more often in the 

 northwestern portion" (Bull. Wis. Nat. Hist. Soc. Ill, 1903, 124). No 

 statement is made as to the authority for the identification of these speci- 

 mens. If this form occurs in Michigan at all we should look for it in the 

 extreme western part of the Upper Peninsula in fall and winter; the fact 

 that Dr. Atkins' specimens were taken in southern Michigan and in late 

 spring increases our doubt as to the identification. 



Willow Thrush. Hylocichla fuscescens salicicola Ridgw. (756a) 



Synonyms: Western Tawny Thrush; Western Wilson's Thrush. 



This is the western form of the Veery, differing but slightly from the 

 typical form, but often decidedly larger and with the spots of the breast 

 somewhat darker. It belongs to the Rocky Mountain region, ranging 

 eastward regular to Dakota and more rarely to Illinois, Wisconsin, and 

 probably to Minnesota. Specimens have been taken at Chicago, 111., 

 Grand Crossing, 111., Liverpool, Ind. (Butler, Birds of Indiana, p. 1151), 

 and a single specimen was taken at Delevan, Wis., May 6, 1899 and identified 

 by Wilham Brewster (Birds of Wisconsin, 1903, p. 126). Mr. P. A. 

 Taverner of Detroit writes "I believe that Saunders has taken it at London, 

 Ont. and Fleming at Totonto, Ontario. * * * j beheve that all 

 specimens taken after September 15 or 20 can usually be referred to this 

 form." We have not had opportunity to examine any suspected specimens, 

 but collectors should be on the lookout for this subspecies. 



Greenland Wheatear. Saxicola oenanthe leucorhoa (Gmel.). (765a) 



This is a bird of striking plumage, and about the size of a common Blue 

 Bird, native to Greenland, adjacent portions of North America, and Ice- 

 land, but has been recorded also from Quebec, Ontario, New Brunswick, 

 New York, and once or twice from New England, probably while wandering 

 southward on its autumnal migration. 



There are no satisfactory records of the Wheatear in Michigan. 

 "Archer" (G. A. Stockwell) says: "An occasional autumnal visitor to 

 Sanilac and St. Clair counties" (Forest and Stream, Vol. 8, No. 16, p. 241), 

 but cites no specimens. It is not improbable that it may occur at rare 

 intervals, but we have no proof of its presence as yet.
