69. Troglodytes aedon parkmani. Parkman's Wren. — Fairly com- 

 mon all summer. 



70. Nannus hiemalis pacificus. Western Winter Wren. — Common 

 resident; nested along the creek in moss and upturned roots and stumps. 

 One nest on May 20 had four eggs which the bird promptly deserted after 

 I disturbed her. 



71. Certhia familiaris montana. Rocky Mountain Creeper. — Fairly 

 common in March and April, but disappeared with the snow. 



72. Sitta carolinensis nelsoni. Rocky Mountain Nuthatch. — Not 

 common, but a permanent resident. 



73. Sitta canadensis. Red-breasted Nuthatch. — Common resident. 



74. Sitta pygmaea. Pygmy Nuthatch. — Abundant on the high 

 ridges, nesting in dead pine tops. 



75. Penthestes rufescens. Chestnut-backed Chickadee. — Fairly 

 common; young were secured in July, 1906. I believe this record extends 

 the range of this species somewhat.

 — A single example secured on May 30, 1907.

 dent; begins nesting early in May.

 mer resident in the deep fir thickets where their sweet song could be heard 

 daily during May and June. 



79. Hylocichla ustulata swainsoni. Olive-backed Thrush. — Speci- 

 mens sent to the United States National Museum were identified as this 

 species. I know of no other records of H. u. swainsoni being taken in^Ore- 

 gon. Common; arrives about May 13; nests in June and July. 



80. Planesticus migratorius propinquus. Western Robin. — Common 

 summer resident. 



81. Ixoreus nsevius. Varied Thrush. — Not common; a nest found
