From September 19 to 25 is the usual time of its appearance. 

 Eiglit to ten birds frequently constitute a da3''s record. Thirty- 

 birds were observed on October 4, 1904, eighteen on October 10, 

 1907, and fifteen on October 4, 1910. In 1901, 1902, and 1903 

 one or more were still present on October 16, 13, and 14 respec- 

 tively. The song is often heard. Mrs. Bridge informs me that 

 she saw a Ruby-crown in 19 10 at Cherry Pond on September 5, 

 and another in Randolph on September 10. 



179. Hylocichla mustelina. Wood Thrush. 



A somewhat rare summer resident since the j^ear 1902. 

 The song was first heard in Jefferson on May 25 of that year, 

 the morning after my arrival on the Highland, when I stepped 

 forth at an earl}^ hour. The bird was singing at the border of 

 our woods and furnished a happy surprise, as the species had 

 not been known to be in the Jefferson region. It was a month 

 later, June 27, when the song was next heard, this time from a 

 bird on Boy Mountain well up toward the summit, at an eleva- 

 tion of 2000 or 2100 feet. Here on July 4 four birds were located 

 by their song, constituting a promising colony. Mr. Bradford 

 Torrey had first noted the Wood Thrush in Franconia in 1899, 

 hearing two birds in full song in late May and early June of that 

 season. In 1903 the species was found in three localities. Four 

 singing males were again heard on Boy Mountain at about the 

 same altitude as in the previous season ; four others were heard 

 in woodland in the valley, where the elevation is 1200 or 

 1300 feet ; and two others near a hillside road on Mt. Pliny. In 

 1904, a single bird only was heard in the valley, and only one 

 in the Boy Mountain haunt ; but two sang in the piece of wood- 

 land opposite our house throughout June and into July; two 

 others were heard by the roadside in Randolph in the vicinit}^ 

 of the Ravine House ; and three were located near the highest 

 point of the Mt. Madison road to the Glen, at a probable eleva- 

 tion of 1600 feet. The species was evidently extending its 

 breeding grounds. In 1905, the Boy Mountain colony was 

 again strong, numbering five singing males, and again a pair
