 758a. Hylocichla ustulata ustulata (Tschudi). Olive-backed 

 Thrush. 



The Olive-backed Thrush occurs as a breeder in a 

 number of counties where the Canadian element of fauna is 

 well marked. It was first recorded from North Mountain, 

 Sullivan County, where Mr. Dwight found it abundant. More 

 recently Mr. Witmer Stone found it in the same locality. It 

 has also been found breeding in Pike County by Mr. narrower, 

 in Monroe County by Messrs. Carter, Baily, and Stone, in 

 Clinton and Potter Counties by Mr. Cope, and in Warren 

 County by Mr. Simpson. It undoubtedly occurs in other places 

 in the northern tier of counties, where the conditions are 

 favorable. 



759b. Hylocichla guttata pallasi (Cab.). Hermit Thrush. 



In the counties where the Canadian fauna is still 

 present and in the higher Alleghanies as far south as Cambria 

 County the Hermit Thrush is a regular breeder, being especial- 

 ly abundant in the northern tier where the conditions are 

 more boreal. In Monroe and Pike Counties, it is locally a 

 common species but not nearly so abundant as in Sullivan 

 and Warren Counties, where the author has found it breeding 

 in numbers.
