migration flight, although they may only have made an excur- 

 sion from the village either of Whitefield or Lancaster, a few 

 miles distant. Four birds seen in Randolph on August 13, 1909, 

 were undoubtedl}^ in migratory flight. The latest record is of 

 three birds in Lancaster on September 2, 1909. 



129. Petrochelidon lunifrons lunifrons. Cliff 



Swallow. 



A common summer resident, several colonies occupying the 

 eaves of barns in Jefferson and other colonies breeding in the 

 adjoining towns. At a large farm barn on the Highland a num- 

 erous colony regularly breeds. In 1904, on June 16, I counted 

 sixty-five nests arranged along the southeast side belonging to 

 this colony. In 1905, on June 26, there were seventy-five nests. 

 No use is made of the opposite northwest side, with the 

 rarest exceptions. In the more recent years the colony has not 

 been as large until in 1910, when on June 13 seventy-eight nests 

 were counted. On June 27 of the same year a colony possessing 

 one hundred and twenty-seven nests was seen occupying the 

 eaves of a big barn across the Connecticut River in Lunenburg, 

 Vermont. In late July large flocks, sometimes numbering two 

 hundred birds or more, are on the wing and occupy the tele- 

 phone wires. The latest records, year by year, are of a single 

 bird, or a few birds, in the early days of September, seen between 

 the first and the eighth days. In 1904 one was seen on the 

 seventeenth day. 



130. Hirundo erythrogastra. Barn Swallow. 



A common summer resident. Nearly every farm barn has 

 its larger or smaller colony breeding within it. In late July large 

 flocks of adult and yoting birds are seen on the wires. A month 

 later the numbers have considerably diminished, but small flocks 

 are still seen in the early days of September. The latest records 

 are of a single bird on the 23d in 1903, and of three birds on the 

 same date in 1907, after an interval of a week when no Barn
