Lake Umbagog, Maine. 
1897. guttural tones. She alighted about 200 yards off and after 
May 24. swimming about for awhile flew still further away. Watrous 
this morning saw five 'whistlers together in the water not far 
from this nest. Four seemed to be females, the fifth being a 
fine old drake. I should add that when the female flew from 
the hole this afternoon her wings whistled audibly but with a 
hollow tone like that of a humming top. According to my ex¬ 
perience it is unusual for a Vi/histler to sit as closely as 
did this bird. Ordinarily they leave the nest before you can 
have 
run the boat alongside the stub and I^never before known one 
fail to start at the first thump on the fo$t of the stub. 
This nest had 12 eggs; three were fresh, the others rep¬ 
resenting every stage of incubation up to about 7 or 8 days.
