County, but Dr. Cooper once saw large numbers (possibly D. a. rubiginosa) 
“at the Straits of De Fuca,’ on April 8. On the west side of the mountains 
this Warbler may not often nest more than once in a season, but on the 
East-side it usually raises 
two broods. 
The nest of the Yellow 
Warbler is quite common, 
especially easterly, where 
its cover is more re- 
stricted; and no_ special 
pains is taken at conceal- 
ment. Nests may be 
placed at any height in 
orchard trees, alders, wil- 
lows, or even fir saplings; 
but, without doubt, the 
most acceptable site is 
that afforded by dense 
thickets of the wild rose 
(Rosa pisocarpa) where- 
ever found. 
The cradle of this bird 
is of exquisite fabrica- 
tion. The tough inner 
bark of certain weeds— 
called indiscriminately 
“hemp” — together with 
grasses and other fibrous 
materials in various pro- 
portions, is woven into a 
compact cup around, or 
settled into, some stout

full of Warblers’ nests, 
two or more seasons old. A fleecy lining, or mat, of plant-down is a more 
or less conspicuous feature of every nest. Upon this as a background a 
scanty horse-hair lining may exhibit every one of its strands; or again, as 
in the case of a nest taken on the Chelan River, the eggs themselves may 
be thrown into high relief by a coiled black mattress.
