September 30 and October 7. In 1905 fifteen birds were noted, 

 twelve being in the valley on October 11. In other seasons one 

 to four birds onl}^ have been seen. The range of date has been 

 from September 22 in 1910 to October 11 in 1904 and 1905, but 

 lies chiefly in October. Mrs. Bridge informs me that she saw 

 two birds in the vicinit}^ of Cherry Pond on September 15, 1910. 



158. Seiurus aurocapillus. Oven bird. 



A common summer resident in mixed woods on the moun- 

 tain slopes and in the valle}', but not found high on the 

 mountains. In following trails up the mountains the song is 

 rather soon left behind. The song period extends usuall}' 

 through three weeks of Jul3\ Later the song is seldom given, 

 although it has been occasionally heard at various times in 

 August and even early September. Many times the flight-song 

 has been enjoyed. Eight to ten pairs occupy the fifty-acre piece 

 of Highland woodland. In some seasons sixteen to eighteen 

 singing males have been recorded in making the ascent of Boy 

 Mountain from the Highland road, these being located between 

 the elevations of 1600 and 2200 feet. Individuals are seldom 

 seen after the nesting season, seeming not to come under observa- 

 tion, although they may still be within the wood ; but occasion- 

 all}' one is seen walking on the ground or upon the bough of a 

 tree. Very few birds have been recorded in September, and 

 these have been seen late in the month as frequently as early. 

 I have only two October records, a bird on October 8 in 1904 

 and one on October i in 1906. 



159. Seiurus noveboracensis noveboracensis. Water- 



thrush. 

 A not uncommon summer resident along the brooks and 

 rivers on the lower mountain slopes and in the valleys. Along 

 Israel's River in its course through the Jefferson valley ten sing- 

 ing males were noted in 1905. In 1907 thirteen were recorded 

 along the same extent of the river. In the last three seasons 

 there have been fewer birds. In 1904, 1905, and 1906, in the
