21. RUFFLEHEAD— r/zfln7o/;r/^7 albcohi. 



Formerly common, now a rather rare Winter resident, No- 

 vember to April. Both fresh and salt water. 



22. OLD SQUAW— Harclda hycinalis. 



Very abundant Winter resident. Arrives from the north 

 in late October or early November. Leaves in late March or 

 early April. This is a very noisy bird and is a characteristic 

 feature of the Sound in Winter. A large flock feeding over the 

 shallows keeps up an incessant chorus of nazal sounds resem- 

 bling the syllables awar-awar-arr, awar-awar-arr. Old Squaws 

 come well up the harbor but not so far as the Golden-eye or 

 Scaup. 



23. KING EIDER — Somafcria s[^cctabilis. 

 Occasional Fall migrant and Winter resident. 



24. AMERICAN SCOTKR~0 idciiiia amcricana. 

 Rare, young birds occasionally common in Fall. 



25. WHITE-W^INGED SCOTER— 0/Wc'////o dcglandi. 



This with the following species are collectively the commonest 

 (lucks in the Sound off New Haven in the Fall and Winter. 

 They are called Coots by the gunners and are at times almost the 

 only birds taken in the "duck lines" along shore, altho they are 

 not edible by reason of their fishy taste. It is often difficult to 

 distinguish between these birds at any great distance ; and since 

 their habits are about the same, they may be treated together. 

 The White-winged is the commonest, the American the rarest. 

 They arrive from the north late in August or early in September, 

 but at first keep well off shore and are not much seen. Towards 

 the middle of September they become common and during Octo- 

 ber and November are very abundant. The last leave about 

 May I. Often seen flying over the city at dusk during Spring 

 migration. Not known to occur on fresh water about here.
