lined almost entirely with soap-root fiber, which appears to be the usual material 
employed. This nest and its situation is shown in the accompanying cut. On 
June 10, 1901 at Slippery Ford a nest was found built among an accumulation of 
dry black oak leaves beneath a deer-brush on the side of a gulch. It contained 
five egg', two-thirds advanced in incubation at this date. As is shown by the 
above nesting records, five eggs constitute the usual set and the eggs are laid 
from May 20 into June, according to altitude. This warbler was observed com- 
monly at Echo, where the hillsides echoed with its .song. 
[Rather common at (lien Alpine in the thickets of Ceanotiuis cordidatus and 
on the slopes of Mt. Tallac to at lea.st 8000 feet. While the female is usually seen 
in shrubber}" near the ground the male is more often seen and heard singing in 
trees of considerable si/.e. W. W. P.] 
Helminthophila celata lutescens. Lutescent Warbler. One specimen shot at 
I'^yffe in June, 1897, I should consider it an irregular summer visitant in the 
region. Mr. Taylor sent me two females shot near Olen Alpine Springs on 
September 17 and 18, 1901, doubtle.ss migrants. 
[Rather common in the willows and tamarack pines in Glen Alpine and on 
Silver Creek to at least 8000 feet in July and August. I have no evidence that it 
breeds. W. W. P.] 
Dendroica aestiva. Yellow Warbler. At Fyffe this species occurs commonly, 
mingling with the other warblers in the black oaks. On June 16, 189S, while 
crawling through a patch of deer-brush in search of thick-billed sparrows’ nests, I 
noticed a small nest three feet up in the top of a bush and it was presently 
claimed by a yellow warbler. The contents were two advanced and one infer- 
tile egg. The nest was composed of the usual grayish plant material and did not 
differ from nests found in the valley. Personally I have not observed this species 
above Fyffe. 
Dendroica auduboni. Audubon Warbler. A fairly common species at Fyffe 
and upward to the summit. It vies with the hermit warbler in keeping close to 
the conifer.s, and the male in breeding plumage is a bird of rare beauty. All the 
nests I have found have been at comparatively low elevations in the trees, but the 
birds are frequently seen high up in the tall pines and firs, where it is likely that 
many of them nest. Audubon warbler, although not nominally a bird of the 
Transition zone, was observed most commonly at about 3,500 feet altitude below 
Fyffe where a dense growth of cedars had sprung up after a forest fire. This 
seemed the center of abundance and a number of pair were nesting within a 
small area. June 15, 1897, I found a nest 4)^ feet up in a small cedar sapling, 
built next to the trunk. It contained a single egg and had evidently been de- 
serted. The nest was generously lined with feathers, prominent among which 
were several of the plumed quail. On June 5, 1900 at 3,500 feet altitude a nest 
was found 20 feet up on a drooping pine limb, containing full-fledged young. The 
parent birds showed the direst distress, dragging themselves about on the ground 
in their attempts to mislead us. At the P'orni meadow, altitude 7,500 feet, on 
June 10, 1900 I found a nest 15 feet up on a horizontal limb of a red fir, contain- 
ing four fresh eggs. The outside of the nest was composed of plant .stems, the 
inner section of bark strips and grass, with a lining of horsehair and feathers. 
The eggs were heavily marked for this species, being blotched confiuently with 
uml)er and lilac. The nests of this warbler are larger than those of any of the 
other Sierra warblers, while the eggs have a distinctive coloration. 
Dendroica nigrescens. Black-throated Gray Warbler. Common about Fyft’e 
and observed as far up as Slippery Ford. Of all the warblers it seems to be the
