38 BIRDS OF OHIO. 



mer resident in the northern parts of the state, but I find no 

 corroborative evidence to that effect. It is more often seen 

 in pairs or singly than the Mallard, and appears to be less 

 wary, frequenting small ponds and streams which the Mal- 

 lard avoids. 



The migrations occur at the same time as the Mallard, 

 with possibly a little earlier return in the autumn. 



29. (133a.) ANAS OBSCURA RUBRIPES Brewst. 



Red-legged Black Duck. 



Henninger, Wilson Bulletin, No. 41, 1902, page 134. 



The recent addition of this subspecies to our fauna makes 

 any statement about its range in the state of little value. It 

 seems likely to be found not uncommon during the migra- 

 tions, probably in company with the Black Duck. Collec- 

 tions seem to indicate that this is the more common form for 

 Ohio, if it does not prove to be the regular migrant to the 

 almost exclusion of the other form. Ohio collections con- 

 tain both forms. 



30. (135.) CHAULELASMUS STREPERUS (Linn.). 249. 



Gadwall. 

 Synonyms: Anas strepera. 



Gray Duck. 

 Kirtland, Ohio Geol. Surv., 1838, 166, 186. 



The Gadwall appears to be rare as a migrant. Reports 

 are not only few but generally unsatisfactory. It is cer- 

 tainly among the disappearing ducks in Lorain county. 

 Prior to 1885 it was one of the market ducks on the lake 

 shore, but it is not seen there now. I have no migration 

 records that will give any idea of the movements of this 

 species. 



31. (137.) MARECA AMERICANA (Gmel.). 251. 



Baldpate. 



Synonyms: Anas americana. 



American Widgeon. 

 Kirtland, Preliminary Report, Ohio Geol. Surv., 1838, 67.
