YELLOW-RUMPED WARBLER. 251 
recent description of it was published, I was convinced that Audubon’s 
statement, that it nested on low trees and bushes, was not true of the bird in 
this latitude. Three nests of this bird have been described; one, by Dr. 
Brewer, from Drummondsville, Ontario, Canada, the others, from Kast Pen- 
field, Monroe Co. N. Y., and Mount Carmel, Illinois, by Prof. J. A. Allen. 
These were all in trees from 20 to 50 feet from the ground. They 
were constructed of grasses and fibres of bark, lined with fine grass, 
and more or less completely covered with lichen, bound on with spiders 
webs. The eggs are dull creamy white, more or less thickly covered with 
blotches of reddish brown. They measure .66 by .47 of an inch. 
During the mating season the males have severe and long continued 
contests. I have seen them fight for hours, often resting from sheer ex- 
haustion. To these contests the female appears to be noi only a disin- 
terested but uninterested spectator, and, keeping in the lower branches 
of the trees, eats and wipes her bill, and eats and wipes her bill, as if 
considerations of celibacy, monogamy or polygamy never entered her 
head. The young are fledged by the last of June.
