HARELDA HYEMALIS. 
The Old Squaw comes rarely to the Lake and then only in 
severe gales. Four have been taken, and forty-six others 
identified. Most of these last were simply hunting around 
for shelter during a storm, and often did not alight, or 
only stayed on the Lake for a few minutes. These are 
such strictly salt water ducks that they seem to have an 
instinctive fear of small lakes.

The three Scoters are poorly represented among the 
ducks shot, one hundred and twenty-three in all, or four 
per cent. Note of the species was not always made but I 
think they occur in the Lake in about the following propor¬ 
tion: American Scoter five per cent, White-winged Scoter 
seventy per cent, Surf Scoter twenty-five per cent. Some¬ 
times considerable flights of Scoters are seen passing over, 
high up. 
ERISMATURA JAMAICENSIS. 
The Ruddy used to be one of the commonest ducks on the 
Lake, easily second to the Black Duck, but it shows a very 
real decrease. The total number is four hundred and 
thirty-one, or over fourteen per cent of all ducks, but I 
think this is really too high, and should be reduced to ten 
or twelve per cent, for various reasons; chief of which is 
the unsuspicious nature of the bird. For the first decade, 
three hundred and twelve were shot, and one hundred 
and forty-nine others noticed. In the last decade only 
one hundred and one were taken and forty-three others 
seen. Thus there appears to be a decrease of nearly 
seventy per cent. One factor, namely, the great increase 
in street-lighting in the neighborhood of the Lake, may have 
had some deterant effect in recent years; for of course all 
Ruddies come into the Lake at night, or just at the break 
of day.
