Swallows (Family Hirundinidae). 



98. Kough-winged Swallovv ( Stelgidopteryx serripennis y

100. Barn Swallovv (Chelidon erythrogaster, Boddsert).

101. Cliff Swallovv {Petrochelidon lumfrons, Say). 



Summer resident. Observed by Audubon, nest- 

 ing at Newport in 1819. 



102. Martin (Progne subis, Linn.). 



A very abundant summer resident. At Lexing- 

 ton these birds assemble in the latter part of the 

 summer in an immense flock. For several years 

 they have made some maple trees on a retired 

 corner of the State College grounds their place of 

 assemblage. As early as July 4 they begin to 

 gather on these trees to roost at night, Coming at 

 about 5 o'clock p. m. from the surrounding coun- 

 try for miles. In August thousands of the birds 

 are every night gathered on these trees. When 

 settlingfor thenightthey make a deafening clatter, 

 quite unlike that produced when about their nests, 

 and are so numerous that the branches sway and 

 bend under them. On one occasion I secured a 

 half-dozen specimens by throwing stones among 

 them. They disappear suddenly about the 25th of 

 August, though a few stragglers may be seen as 

 late as Sept. 1, gathering upon the to wer of the 

 State College building of evenings.
