woodland on the Highland. While on the Cherry Mountain- 

 Bretton Woods drive but four singing males were recorded on 

 June 19, where twentj- -one were heard in 1910 and twenty-seven 

 in 1909. 



163. Wilsonia pusilla pusilla. Wii^son's Warbler. 



As a summer resident there was a smaller representation in 

 the usual haunt in the valley than in 1910, since but four sing- 

 ing males were recorded on June 15, and this proved to be the 

 maximum number for the season of 191 1. 



179. Hylocichla mustelina. Wood Thrush. 



The Wood Thrush continued to be represented by two 

 nesting pairs at least on Boy Mountain in the season of 1911. 

 One other bird was heard singing in the fifty-acre piece of wood- 

 land on the Highland on June 13 and 15, but not longer. In 

 other localities in which the species had been found in recent 

 years the song was not heard. I am informed, however, by 

 Mr. T. Otis Fuller that he heard the song upon many days in 

 the vicinity of the Ravine House in Randolph from a bird located 

 there. Thus the diminished representation of 19 10 was con- 

 tinued in the season of 191 1. 



184. Hylocichla guttata pallasi. Hermit Thrush. 



The Hermit Thrush hardly held its position on the High- 

 land as an abundant bird in the season of 19 11. While the song 

 was heard here and there, it did not prevail as usual. The same 

 decrease was noted in other localities in the region, as the record 

 of every drive and walk indicated. 



185. Planesticus migratorius migratorius. Robin. 



The Robin in the season of 19 11 was present on the Highland 

 in plainly increased numbers. While it had previously been a 

 fairly common bird, it became more common, and the relative 

 numbers of Hermit Thrushes and Robins for the season were 

 reversed, Robins becomings the more numerous.
