never fouud its nest nor have I any record of seeing it in July. It may fre- 

 quently be seen in May and early June circling about over the fields and 

 pastures in the dusk of evening or even on dull cloudy days, but it is most 

 abundant in August and early September, when considerable numbers may 

 sometimes be seen flying about over the meadows and otlier open places.

106. Ch.etura pelagica (Linuipus). chimney swift. (423) 



An abundant summer resident. Formerly nesting in hollow trees and 

 similar situations, but now almost invariably in chimneys. The only 

 nest I ever found in a tree I discovered in the hollow of a liickory stub on 

 my father's farm near Burlington in the spring of 1883. The chimney of 

 our house on the home farm always had its colony of four to six or 

 more pairs of chimney swifts every summer, and it was astonishing the noise 

 they would make, not only throughout the day but also at night, seriously 

 interfering with one's sleep. 



Carroll County: July 14, 1882. set of four fresh eggs. In 1884, first noted 

 April 27 ; common next day. 



In 1884. a pair of chimney swifts fastened their nest to the inside of tlie 

 door of an outhouse at the Vandalia depot in Camden. The birds entered 

 the building through a small hole in tlie gables. The building was in daily 

 use, but those who visited it were cautioned by the railroad agent to open 

 the door carefully so as not to jar the eggs. Usually the bird sitting on 

 the eggs would leave the house when any one entered, but sometimes she 

 would remain on the nest. Four eggs were laid, one of which was jostled 

 from the nest, the other three hatched and the birds grew to maturity. This 

 nest was repaired and used again in 1885, and in 1886, and a brood raised 

 in each of those years. April 17. 1885, noted. 



In the fall of the year the chimney swifts resort in great numbers to 

 some one chimney in the neighborhood. At Bloomington, they frequented 

 the chimney of the University engine house : in Terre Haute, vast numbers 

 used the chimney of the Baptist church on North Sixth street ; while in 

 Carroll County, they have for many years resorted to the chimney of the 

 Methodist church in Flora.
