35. Dafila acuta. Pintail. — From late fall until April one of our 

 most abundant ducks. 



36. Aix sponsa. Wood Duck. — Formerly a not uncommon summer 

 resident in this immediate locality, but now seldom noted. 



37. Marila americana. Redhead. — Occurs as a rare migrant. 



38. Marila valisineria. Canvas-back. — Common from November 

 until April but most abundant during winter. 



39. Marila marila. Scaxjp Duck. — Same as the preceding, M. 

 valisineria, with which it is often found associated. 



40. Marila affinis. Lesser Scaup Duck. — More or less common 

 during the winter months. 



41. Marila collaris. Ring-necked Duck. — Regard this species as 

 uncommon, as have noted it but a few times and during the winter months. 



42. Clangula clangula americana. Golden-eye. — Not uncommon 

 as a winter resident. 



43. Charitonetta albeola. Buffle-head. — Common winter resi- 

 dent, departing in April. 



44. Harelda hyemalis. Old-Squaw. — Observed from November 

 until April but most common during the winter months. 



45. Histrionicus histrionicus. Harlequin Duck. — A rather rare 

 species during the winter and have noted it until May. 



46. Oidemia americana. Scoter. — A regular but rather uncom- 

 mon winter resident. 



47. Oidemia deglandi. White-winged Scoter. — Common from 

 November until May. 



48. Oidemia perspicillata. Surf Scoter. — Common winter resi- 

 dent. 



49. Erismatura jamaicensis. Ruddy Duck. — Formerly rather 

 common during the migrations but of late years has not been so often noted. 



50. Chen hypoboreus hypoboreus. Snow Goose. — On two occa- 

 sions have seen on the sound near Seattle small flocks of what we regarded 

 as this species. But on the lower sound flocks of white geese are quite 

 regularly observed during the migrations. 



51. Anser albifrons gambeli. White-fronted Goose.— Not un- 

 common as a spring and fall migrant. 



52. Branta canadensis occidentalis. White-cheeked Goose. — 

 More or less a regular migrant. 



53. Branta canadensis minima. Cackling Goose. — A rare mi- 

 grant. 



54. Branta nigricans. Black Brant. — From observations the 

 most common of the Anserinae. A regular spring and fall migrant and 

 common white/ resident but seemingly restricted during this period to 

 certain localities on the sound, doubtless on account of its food supply. 

 A very easy bird to decoy. Generally arrives about the first of December 

 and last seen during April. 



55. Olor columbianus. Whistling Swan. — A regular but not 

 common migrant.
