was common around the shores of the lake, and in the woods might be 
seen woodpeckers of several species. Cabanis’s woodpecker was not 
uncommon, Batchelder’s woodpecker was occasionally seen and heard, 
one pair of red-naped sapsuckers was seen for a day, the lordly pileated 
woodpecker made announcement of his presence by his loud call and hard 
and slow pounding on the trees, while the red-shafted flicker was seen 
and heard daily. At dusk the western night hawk occasionally was seen 
in the air, while during the day, strange as it may seem, an occasional 
humming bird was seeking food from the various flowers about the lake. 
The sharp and far-away sounding call of the western wood pewee was 
frequently heard on the hillside. Wright’s flycatcher was common in the 
timber south of the lake. The black-headed jay was not uncommon, and 
a single curious Rocky Mountain jay was one day seen lurking around 
camp. Higher up on the mountain, above 4,700 feet, Clarke’s nutcracker 
was found. In the woods adjacent to the lake the American crossbill 
was common, and pine siskins were frequently noted in the air overhead 
or occasionally were seen in camp having come for crumbs. Everywhere 
on the reservation where observations were made the western chipping 
sparrow was found. Around the lake Shufeldt’s junco is abundant. Black- 
headed grosbeaks were not seen about the lake, but at the ponds a mile to 
the south they were abundant. The brilliant Louisiana tanager was every- 
where to be seen, while the handsome cedar waxwing was frequently no- 
ticed at the pond with the grosbeaks. The red-eyed vireo, warbling vireo, 
Audubon’s warbler, Townsend’s warbler, and Macgillivray’s warbler were 
the insect feeders noted in the trees. The Rocky Mountain creeper was 
only occasionally seen, though the slender-billed nuthatch is common. 
Every walk brought to view the long-tailed chickadee. The notes of the 
olive-backed thrush were regular features of the woods. A single pair 
of western robins were feeding the young on the nest during the stay at 
the lake. 
The region seems to be a place of resort for birds, where they come 
for a time and disappear, as is the case with the region as far as man 1s 
concerned. Later investigations may reveal more. 
CONCHOLOGY OF SINYALEAMIN LAKE, 
One would expect to find an abundance of shells in and around such 
a body of water as this lake. In this, as in many other points, there is 
disappointment. These clear cold lakes do not offer a large supply of 
food for such dainty feeders as shells and the supply is not abundant. 
The small alpine form, Pyramidula strigosa, var. alpina, has been 
previously referred to as having been found near the summit of the 
mountain. In the woods along the borders of the lake the larger Pyra- 
midula strigosa Gld., var. cooperi W. G. B., was taken rather abundantly. 
With the preceding P. solitaria was found in less abundance.. Only a 
few Polygyra townsendiana Lea, var. ptychophora A. D. Br., were taken. 
These two have so far been found together, tue former most abundantly, 
the latter much less so. These four land species were all that could be 
found. In the water three more species were taken, all sparingly. 
Physa heterostropha Say was not abundant, but several large and very 
fine specimens were taken. Now and then Pianorbis trivolis was seen.
