been recorded upon various dates in June and July. At several 

 other points in the valley single pairs have been located as far 

 up as the foot of the Highland. 



Here and there in the village of lyancaster a pair locates in 

 a house-shed upon its principal streets. In 1910, on June 27, 

 one was heard singing on the shed-roof of a house in Jefferson, 

 situated in the Starr King district on the side of the mountain 

 at about 1400 feet elevation. The song period extends into the 

 early days of August. 



Occasionally in September one or two birds have been seen 

 on the Highland. In 1901 one was seen singing on the tenth 

 day and again on the thirteenth on a pile of brush in a pasture ; 

 and in 1908 on the ninth day one was heard singing. These 

 were probably migrant birds. The latest records are September 

 24 and 25, except in 1908, when three birds were seen on Octo- 

 ber 3 in the valley and one on October 5 on the Highland. 



170. Nannus hiemalis hiemalis. Winter Wren. 



A common summer resident of the forests from the valley 

 bottoms to almost the limit of tree growth on the mountains, 

 found along the brooks. It has become less common with the 

 felling of the trees and the opening up of the forests to the sun. 

 Along the Jefferson Notch road, following the South Branch, 

 eight to ten years ago twice as many singing males were recorded 

 as in more recent years. Then the road led through forest only 

 partially despoiled. Now along its entire course the lumbermen 

 have taken pretty much all of the well niatured coniferous trees, 

 and the thinness of the standing woods makes them far less 

 desirable to the wrens. The song period extends through July 

 and a week or more of August, and the song is occasionally 

 heard even a month longer and sometimes in late September. 

 Some individuals have been recorded up to the middle of Octo- 

 ber and doubtless linger in the region much later.
