from several birds far up in Tuckerman's Ravine, about the 

 " Perch Camp " at the head of the Ravine of the Cascades on 

 Mt. Adams, in the Jefferson Notch, as well as elsewhere on 

 the Presidential Range, and in the ravines of Mt. Starr King. 

 The song period extends to about the middle of July. Twenty 

 to thirty singing birds have often been recorded when we have 

 been following the valley and turnpike route to I^ancaster, or 

 when taking the Cherry Mountain-Jefferson Notch drive to and 

 through Bretton Woods. Some individuals are usuall)- seen up 

 to the last week in September. The latest birds observed were 

 seen on October i in 1901, on October 3 and 4 in 1904, on Octo- 

 ber I in 1906, and on October i and 3 in 1908, a single bird in 

 each instance. 



143. Vermivora peregrina. Tennessee Warbi^er. 



A rather rare fall migrant. One or two only are commonly 

 seen each season in earl}^ or mid-September. These are usually 

 found in the valley. But in 1910 at least a dozen different birds 

 were observed betw^een August 29 and September 20. On 

 August 30 five were seen in the grove of birches at the Mead- 

 ows. On September 3 three were seen in the vicinity of Cherry 

 Pond along the track of the Maine Central railroad. On Sep- 

 tember 10 two were on the Highland at the roadside, and one of 

 these sang. On September 20 two w^ere seen in the valle}- at the 

 foot of the Highland. This is the latest date on which one has 

 been observed. Mrs. Bridge informs me that she saw one in 

 Randolph on September 11, 19 10. 



144. Compsothlypis americana usneae. Northern 



ParuIvA Warbler. 



A common summer resident in all the woodlands and in the 

 forests on the lower slopes of the mountains. Eight to ten pairs 

 season by season occupy the fift3'-acre piece of woodland on the 

 Highland. I have not observed the species when ascending 

 the paths on the higher mountains above the lower levels. The
