WARBLERS: CERULEAN WARBLER 
619 
At Lake Burford, in May and June, 1918, when Doctor Wetmore 
found them nesting “in fair numbers in the yellow pine areas surround¬ 
ing the lake,” the “males were found singing from the tops of the tallest 
pines and were slow and leisurely in their movements, in great contrast 
to their habit at other seasons. Frequently while singing they remained 
on one perch for some time, so that often it was difficult to find them. 
The song resembled the syllables isil tsil tsil tsi tsi tsi tsi” (1920a, p. 409). 
An Audubon Warbler's nest found by Doctor Grinnell in California 
had the wing and tail feathers of j uncos and other small birds mixed 
with its grasses and plant fibers, and was thickly lined with Mountain 
Quail feathers, some of the chestnut-colored ones sticking up above 
the rim conspicuously (1908, p. 112). In New Mexico, Mr. Jensen 
has found their nests lined with the feathers of Bluebirds and Long- 
crested Jays. If a nest with young is discovered, he says, “both parent 
birds try every means possible to draw the attention of the intruder 
away from the nest.” He has seen them “drop with folded wings 
from the top of a tree and flutter among the leaves as if each had a 
broken wing” (1923b, p. 465). 
In their role of flycatchers, J. G. Tyler has found that they not 
only “share with Say Phoebes the habit of catching flies from a window,” 
but sometimes become “so engrossed in this occupation as to cling for 
several seconds to the screen where a south-facing window affords a 
bountiful supply of this kind of food” (1913, p. 100).
