History. 



I can well remember when this bird was a common and 



familiar sight on the ponds of Worcester County and was 



abundant on the Connecticut, Concord and Sudbury rivers; 



but it has become comparatively rare in inland Massachusetts 



in recent years, and like all our Ducks has been driven from 



its former haunts in the interior by incessant persecution. 



On the Charles River in the Back Bay district in Boston, 



and on some of the reservoirs where no shooting is allowed, 



this species has increased recently in numbers, which shows 



that it is not much afraid of people, buildings or boats, but 



is driven away mainly by shooting. My correspondence 



with over three hundred gunners and other observers seems 



to show conclusively that the species has decreased greatly 



throughout the State within the thirty years prior to 1909. 



Only ten correspondents note an increase in the species, and 



sixty-two note a decrease. Even in Barnstable County, 



where five observers report an increase, eighteen report a 



decrease. Mr. Clement A. Cahoon of Harwich states that 



fifty-five to sixty years ago Whistlers came into a large pond 



there by hundreds. People came five miles or more to shoot 



them. Now (1908) he says that he would " about as much 



expect to see a bullfrog flying over the narrows to that 



pond as to see Whistlers." Mr. Samuel L. Buffington of 



Touisset says that Bluebills, Whistlers and Sheldrakes have 



decreased at least seventy-five per cent, in the river near his 



home. Where there were formerly flocks of one hundred to 



two hundred they now see flocks of two or four to a dozen.
