PODICIPHLE. 
90. Podicep8 (JEcmophorus) occidentalis Lawr.—Western Grebe. 
Breeds abundantly in Washoe Lake. The young still in the down were taken August 
31. One of the main subgeneric characters of this bird is the absence of colored ruffs 
or other nuptial ornaments about the head during the breeding season, it thus forming 
a striking exception to the general rule obtaining in the family. The young, the first 
I believe ever taken, are now before me, from the above locality. They scarcely need 
description, more than that conveyed in the general statement that in the distribution 
of colors they almost exactly resemble the old birds. In this respect they seem to 
carry out the peculiarities of their parents, inasmuch as the young of the other grebes 
are all, so far as I am aware, curiously streaked or mottled in their first or downy 
plumage.

LIST OF BIRDS OBSERVED ON THE EASTERN SLOPE OF THE SIERRAS, NEAR CARSON CITY, 
NEVADA, FROM SEPT. 1G to NOV. 7 WITH NOTES. 
TURDIDiE. 
1. Tardus migratorius L., var. propinquus Ridgw.—Nevada Robin. 
During the month of September the Robins began to be rather numerous along the 
mountain sides, the number of those resident here during the summer having doubt¬ 
less been increased by the arrival of birds reared farther to the north, while they were 
rendered more conspicuous from the fact of their having flocked. In early November 
they were seen in great flocks at different localities, where were found various kinds 
of wild berries. The majority of these birds, if not all, pass farther south to winter. 
2. Tardus ncevius Gm.—Varied Thrush. 
A male of this species which I saw confined in a cage in a store in Carson City was 
said by the owner to have been captured during the previous spring in the adjoining 
mountains. For this statement I cannot vouch, but give it for what it is worth. This 
thrush has never been recorded from any locality east of the Sierras; yet there seems 
to be no reason why during the migrations, as in the case of other birds possessing a 
similar summer habitat, the species may not occur along the eastern slope. That it 
actually does so, however, remains to be proven. 
SAXICOLID.E. 
3. Sialia mexicaua Sw.—Mexican Bluebird. 
During the month of September and early October this species was rather numerous 
among the pines at an elevation of about 7,009 feet. After this fewer were seen, a par¬ 
tial emigration having perhaps taken place, or, as is more likely, the species having re¬ 
tired from the high altitudes to the valleys, where they winter in considerable numbers. 
4. Sialia arctica Sw.—Arctic Bluebird. 
At the time the preceding species began to diminish in numbers the present bird 
attracted attention by a corresponding increase, and it soon almost wholly represented 
the other in the mountain region. They winter among the pines and in the brushy 
ravines, forming a close association with the Titmice, Nuthatches, etc. 
SYLVIID^E. 
5. Itegulus calendula (L.).—Ruby-crowned Kinglet. 
Abundant during the fall months among the pines, sometimes in small companies of 
their own species, but more often distributing themselves by twos and threes among 
the flocks of winter birds. 
PARIDiE. 
G. Lophophanes inornatus (Gamb.).—Plain Titmouse. 
A resident, but not very numerous. Inclined to favor with its presence the cedar and 
piiion hills rather than the pine region proper, from which, however, it is not entirely 
absent.
