36. Oidemia americana Swains. 

 American .Scoter. Butter-bill Coot. Butter-bill. 



Transient visitor in autumn, of infrequent and apparently rare occurrence. 



Mr. W. A. Jeffries tells me that the American Scoter occasionally alights 

 in the Back Bay Basin in autumn and it has been taken at that season in Spy 

 Pond and in the Mystic Ponds, according to Mr. John H. Hardy, Jr. Among 

 our older local gunners of thirty years or more ago there existed, as I well

 fact. I can give but one definite instance, however, of the occurrence of the 

 American Scoter at Fresh Pond, — that of a fine old male which I saw and vainly

October i, 1868, three seen, one taken, Fresh Pond, W. Brewster. 

 November 26, 1900, six seen, Fresh Pond, W. Brewster. 



I can remember a time ( 1 867 to 1 872) when White-winged Scoters used to 

 alight in Fresh Pond nearly every autumn — usually during October, quite as 

 often in clear as in stormy weather, and almost invariably at daybreak. As a 

 rule they appeared singly or two or three together, sometimes in company with 

 Ruddy Ducks. Nearly all were young birds and so tame that they fell easy
