latter part of June of each j-ear, the song was heard at a point 

 in Pinkham Notch opposite the path leading into Tuckerman's 

 Ravine. The elevation here is about 1900 feet. The song 

 period is very limited, hardly extending beyond the first of July, 

 and, when concluded, the song has scarceh' ?jeen heard even 

 occasionally. In 19 10, however, two birds were heard singing 

 on x\ugust 3, and one from a high perch b}- the roadside at the 

 Meadows on August 18. The latest dates of a bird seen are 

 September i in 1900 and vSeptember 16 in 1907, these being the 

 only vSeptember records. 



160. Oporornis agilis. Connecticut Warbler. 



A somewhat rare fall migrant ; in some seasons several have 

 been noted. The earliest occurrence was in 1904, when on 

 September 6 one was seen in the woods bordering Weeks pond 

 in East Whitefield. Three others were noted the same season. 

 In 1903 five were seen in one day in the valley September 25, 

 constituting the onl}- record for the season. In 1909 five were 

 successively seen in different localities between September 21 

 and 27. In three of the last eight 5'ears onh' a single bird was 

 recorded each season. In 1908 one was seen on October 6 on 

 the Highland, constituting my latest record in the series of 

 years. The more usual time of occurrence is between vSeptem- 

 ber 19 and October 4. Mrs. Bridge informs me that she saw 

 one by the Jefferson Notch road on September 14 in 1908, and 

 one in Randolph on the same date in 19 10. 



161. Oporornis Philadelphia. Mourning Warbler. 



A fairly common summer resident on the edges of woods in 

 the valley, and along the streams up the mountain sides, some- 

 times to an elevation of 2500 feet or higher, in forest which has 

 been logged and is consequently somewhat open and possessed 

 of undergrowth. The full song period extends quite definitel)' 

 to the middle of Jul3% but after a brief period of cessation the 

 song is much heard from a bird here and there throughout Jul}^
