BIRDS OF .MAIM.. 31 



Subfamily FULIGULIN.K. Sea Ducks. 



Genus AYTHYA Boie. 



r>7. (146). Aythya ainericaua (Eyt.). Redhead. 

 A rare migrant through the greater part of the state. It is 

 reported as breeding in Washington County. 



<'c>unty IJeconls. ( 'um!>rrl;m<i. "fairly common" (Brock); Keuuebec, 

 (Dill); Kuox, 'Tare migrant" (I'sicklift) ; Oxford, "not very common" 

 < \:ish) ; Peuobscot, "one shot at Levant, October 26, 1896, and now in 



the collection of the University of Maine' 1 (Knight) ; Washington, u r;itv, 

 breeds" (Boardman). 



58. (147). Aythya vallisneria ( Wtlx.). Canvas-back. 



As there are but two seemingly authentic records for the' state, 

 this species may be classed as a casual visitor without much doubt. 

 There have been other specimens reported, but on investigation 

 they have proved to be the preceding species. The specimen of 

 Redhead recorded from Penobscot County was at first reported as a 

 Canvas-back, but after investigation was found not to be this 

 species. A number of cases reported, where the report was not 

 substantiated by the production of the specimen for identification, 

 have therefore been deemed not worthy of recording. 



County Records. Cumberland, "taken in Casco Bay and at Cape 

 Kli/abeth" (Smith's List of Birds of Maine, Forest and Stream, Vol. 20, 

 p. 184). 



Subgenus FULIGULA Stephens. 



59. (148). Aythya marila uearctica Stejn. American Scaup 

 Duck. 



Common coastwise in migrations, and also occurs some winters. 

 Usually found in large flocks. 



County Records. Androscoggiu, (Johnson) ; Cumberland, "common" 

 (Brock) ; Hancock, "a specimen from this county in my collection" 

 (Knight); Kuox, "winter*' (Rackliff); Sagadahoc, "quite common in 

 fall" (Spinney); Washington, "not common'' (Boardman). 



60. (149). Aythya affinis (Eyt.). Lesser Scaup Duck. 



A rare migrant along the coast, wintering chiefly in the south 

 and breeding north of the state. From its close resemblance to 

 the preceding species it is likely to escape observation except by 

 persons well acquainted with the species.
