throughout the forest in the region from lake level to a considerable eleva- 

 tion, in May its song being heard at almost any time during the da}'. 

 May 21 we noted parent birds accompanied by fully fledged young. It 

 was equally as common in October. 



75. Certhia familiaris occidentalis. California Creeper. — 

 Noted in May and June only, being seen on three occasions in the forest. 



76. Sitta canadensis. Red-breasted Nuthatch. — Although not 

 common appeared quite generally distributed, but was heard more often 

 in the depths of the forest. 



77. Penthestes atricapillus occidentalis. Oregon Chickadee. — 

 From our observations, of rare occurrence in the region, being seen only on 

 two occasions, both in May. 



78. Penthestes rufescens rufescens. Chestnut-backed Chicka- 

 dee. — One of the common birds of the entire region and of general dis- 

 tribution, but more often seen in the deciduous growth along the lake in the 

 proximity of the conifers and the open forest spots. At times observed 

 in the heavy timber associated with R. s. olivaceus, when it would be 

 found near the tops of the tall trees. 



79. Regulus satrapa olivaceus. Western Golden-crowned King- 

 let. — Rather common being well distributed, although noted more fre- 

 quently in the forest on the mountain side. 



80. Regulus calendula grinnelli. Sitka Kinglet. — Quite com- 

 mon as a migrant, the first being seen April 19, the last on May 3. At 

 this time invariably found in company with P. r. rufescens, ovD.a. auduboni, 

 and on occasions all were found associated. 



81. Myadestes townsendi. Townsend's Solitaire. — Our only 

 record is that of a pair we noted in the Soleduck River valley, about six 

 miles west of the head of the lake. It is possible however that the species 

 might prove of more common occurrence in the higher altitudes. 



82. Hylocichla ustulata ustulata. Russet-backed Thrush. — 

 Found quite common throughout the entire region but was partial to such 

 localities as the old clearings and burns that were fringed with a growth 

 of deciduous trees and shrubs. Several times heard in the mountains up 

 to an elevation of 1200 feet. First seen May 21, and by the 27th svas 

 quite generally distributed. 



83. Hylocichla guttata guttata. Alaska Hermit Thrush. — Not 

 uncommon in the region, the first being seen on April 24, from which date 

 its beautiful song was quite often heard in the forest, particularly near the 

 lake. In Autumn was first noted October 9, and at this season we found 

 the species fairly common, but it was more often seen along the narrow 

 beaches overhung with deciduous growth. 



84. Planesticus migratorius propinquus. Western Robin. — 

 One of the common species, being well distributed. It showed a partiality 

 however for the more or less open tracts that in past years had been burned 

 over and later covered with a young growth, and was rather more abundant 

 around the few cultivated areas at the lower end of the lake. Quite often
