were in the air together, indicating the nesting of several pairs 

 in that locality. The same season a nesting was begun in late 

 June in an open field in the valley bottom near the Highland 

 station. Two eggs were laid, and the bird sat upon them sev- 

 eral days, but a few days later the nest was found empty, having 

 been robbed by some unknown agency. 



In 1901 a distinct migration of Nighthawks was witnessed 

 on August 20 and 21. Twenty-five to thirty birds were seen in 

 the air at 5 p. m. of the first day over the Meadows in company 

 with swifts and swallows. On the following day in the late 

 afternoon, as we were returning from the Glen, about twenty 

 birds were seen near the Randolph station, and forty more as 

 we proceeded farther up the valley of the Moose River. In 

 1910, on August 22, a smaller migratory movement was wit- 

 nessed, when twelve birds were seen over the valley moving 

 westward. I have but one September record, namely, two birds 

 seen on the 4th, in 1900. 



81. Chpetura pelagica. Chimney Swift. 



A rather common summer resident, regularly nesting on 

 the Highland and here and there in chimneys in different sec- 

 tions of the town. On June 10, 1907, in a drive of about a 

 dozen miles within town limits, fourteen pairs were recorded. 

 They have nested in one of our own chimneys, and the j'oung have 

 fallen to the hearth. Our neighbors have had similar expcri- 

 iences. Swifts are frequently seen during the summer over the 

 extensive wooded tracts of the Presidential Range. So often 

 have three birds in flight together been recorded at different 

 times and places that we have come to remark of our observa- 

 tion, "There are the usual three." Repeatedly evening after 

 evening and in different seasons the flight of our local band at 

 sundown has consisted of three birds. 



I have seen no large flocks of swifts at the time of their 

 leaving in late summer. A dozen to less than twenty birds 

 constitute as large a company as has usually been observed. 

 But in August, 1910, on the nth and 22d days, at 5:30 p. M.,
