1A.O DwiGHT, Sum liter Birds of the Pennsylvania Alleghanies. [April 



Setophaga ruticilla. American Redstart. — This species was not 

 found at all on the mountains, and but few were observed in the valley 

 region, still it seems strange that it should not occur higher up. 



Galeoscoptes carolinensis. Catbird. — A few seen daily about Cresson ; 

 once detected in the clearing on North Mountain. 



Harporhynchus rufus. Brown Thrasher. — Frequently met with about 

 Cresson and one on North Mountain ; also in the valley region. 



Troglodytes aedon. House Wren. — A few observed about Cresson, 

 though more numerous at Gallitzin, three miles away, where they fre- 

 quented a clearing full of tall dead stubs. None on North Mountain. 



Troglodytes hiemalis. Winter Wren. — Observed on and about North 

 Mountain only, where it was generally distributed throughout the forest, 

 most abundantly in the damper portions. It was especially numerous 

 along Kitchen's Creek. It is a species ever suggestive of cool, secluded 

 forest and moss-covered logs, and its presence always betokens a north- 

 ern tinge of bird life in the region where it is found. Dr. Warren re- 

 cords it as breeding sparingly in the mountains and northern part of the 

 State. Baird did not find it breeding at Carlisle. 



Certhia familiaris amcricana. Brown Creeper. — Occasionally ob- 

 served on North Mountain, where a family of young birds was encoun- 

 tered, not elsewhere. Dr. Warren reports it breeding in the higher por- 

 tions of the State. 



Sitta carolinensis. White-breasted Nuthatch. — Occasionally ob- 

 served, but not common. 



[Dr. Warren says that 6". canadensis breeds sparingly in the higher 

 parts of the State, and this is not altogether improbable.] 



Parus atricapillus. Black-capped Chickadee. — Observed not infre- 

 quently. 



Regulus satrapa. Golden-crowned Kinglet. — Met with but once, 

 a pair on North Mountain along Kitchen's Brook. Dr. Warren says of it : 

 "My friend Prof. August Koch of Williamsport informs me he has occa- 

 sionally met with this species and their young in August and September 

 in Lycoming County. Perhaps future investigators will show that this 

 species breeds sparingly in some of the extensive coniferous forests of our 

 higher mountain ridges." Baird does not record this truly Canadian 

 species as breeding. 



Turdus mustelinus. Wood Thrush. — An abundant species, found in 

 the woods to the highest points. 



Turdus fuscescens. Wilson's Thrush. — Tolerably common about 

 Cresson and in the valley at Altoona. Not met with on North Mountain 

 itself, but seen in the valley eastward. Dr. Warren says that it breeds 

 sparingly in the northern and mountainous parts of the Commonwealth, 

 also in Northampton, Lackawanna, Crawford, and Erie Counties. Baird 

 did not find it breeding at Carlisle. 



Turdus ustulatus swainsonii. Olive-backed Thrush. — Found only 

 on North Mountain, but quite abundant there. I believe there is no 

 record of this species being found in summer south of the Catskill Moun-
