Some seasons the species appears very numerously in the 

 valleys in September and early October, alighting much on the 

 roofs of buildings with Bluebirds, which they chase in sport, 

 and on fence rails and posts, also dropping to the ground and 

 feeding like sparrows. A flock numbering from thirty to forty 

 birds is often found in the grove of birches at the Meadows in 

 late September, with, and sometimes without, other warblers. 

 In autumn drives many are seen along the roadsides. 



149. Dendroica magnolia. Magnolia Warbler. 



A common summer resident of the coniferous growth of the 

 Highland and along the water-courses, also of the mountain 

 sides to high altitudes, and a common fall migrant. In 1902 a 

 bird was heard singing at about 4000 feet elevation on Mt. 

 Adams. Three or four pairs breed season by season in the 

 fifty-acre piece of Highland woodland. The song period extends 

 with little interruption throughout July and into the early days 

 of August, and occasionally the song is given later in the month. 

 Many singing males have been heard when the Cherry Moun- 

 tain-Jefferson Notch drive has been taken from time to time, 

 about twenty miles of which is through forest of mixed growth, 

 the number ranging between twenty-five and forty-five songsters. 

 Many are seen in the fall migrations in the general movements 

 from the mountains and be\^ond to the Connecticut valle}\ The 

 latest records for an individual are October 3 and 7 in 1900, 

 October 4, 6, and 8 in 1904, October 4 in 1908, and October 1 

 in 1910. 



150. Dendroica pensylvanica. Chestnut-sided 



Warbler. 



A common summer resident of clearings and of forests 

 which have been logged, thus leaving the standing trees sparse 

 and with young growth springing up, also a common fall 

 migrant. It is not found, however, on the mountain sides far 

 above the lower levels, or about 2000 feet. The song pciiod
