° 1915 J Willett, Birds of Forrester Island. 305 



Passerella iliaca townsendi. Townsend's Fox Sparrow. — Probably 

 the most abundant land bird on the reservation, occurring in wooded locali- 

 ties everywhere. Seemingly at least two broods are raised in a season. 

 The location of the nests noted varied greatly, some being ten or twelve 

 feet up in trees, some in brush thickets and on fallen logs and others on the 

 ground. A brood of young left a nest near camp May 24 and fresh eggs 

 were found as late as June 22. 



Vermivora celata lutescens. Lutescent Warbler. — Common in 

 brush thickets and on grassy slopes in many different localities. Was 

 evidently breeding during the month of June but no nests were found. In 

 late July the adults appeared accompanied by the young and from that 

 time on the species was very abundant in the young spruce timber. 



Nannus hiemalis pacificus. Western Winter Wren. — Common 

 throughout the wooded sections. Full grown young appeared by June 18. 



Certhia familiaris occidentalis. California Creeper. — Rare. 

 Seen occasionally in the woods throughout the summer. 



Penthestes rufescens rufescens. Chestnut-backed Chickadee. — 

 Fairly common during the first part of the summer. Abundant after July 

 10. 



Regulus satrapa olivaceus. Western Golden-crowned Kinglet. — 

 Common. During early summer kept mostly to the treetops, but by the 

 latter part of July was plentiful everywhere. 



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

 dant in the timber in all parts of the reservation. From June 14 to July 2 

 several nests containing eggs and young were found. The locations of 

 these varied greatly, some being low down in salmon-berry thickets, some 

 in roots of fallen trees and others in crevices in stumps. In nearly all cases 

 the nests were beautifully covered with green moss. Some young birds 

 were flying by July 10 and shortly after that date they were plentiful. 



Ixoreus naevius nsevius. Varied Thrush. — Much less common than 

 the last species but fairly well distributed throughout the timber. Fully 

 fledged young appeared the last week in June.
