Clangula clangula araer ioana . 
Lake Umbagog, Maine. 
1896. ■ On my way across the Lake I saw four Whistlers, two old 
birds, the other two young not raore than half grown. Unlike 
Aug.13. the Black and Wood Bucks which keep together in broods until 
they leave for the south the young Whistlers apparently sepa¬ 
rate long before they are large enough to fly and probably as 
soon as they are able to get their own.living. They utter a 
low queer , queer almost exactly like that of the Black Duck 
(I have always supposed that this note is peculiar to the 
young drake of the latter species but I hear it as late as 
October after the Black Ducks are fully grown) 'and having the 
same peculiar shrill yet husky treble tone. The little fel¬ 
lows which I saw to-day were expert divers and had already 
learned the art of doubling back when hard pressed but they 
were so tame that I could have shot them easily enough. They 
feed both by.diving and by skimming the surface of the water 
with half opened bills. During the day they work well in 
shore into the grassy coves and up the river but before sun¬ 
set they paddle out into the Lake a little way and spend the 
night 200 or 300 yards off the mouth of the river. I have 
seen no old birds in this neighborhood after sunset and sus¬ 
pect that, in accordance with their old-time custom, they pass 
the night at the head of the Lake but if so I have not as yet 
seen them going or returning.
