Harris Birds of the Kansas City Region. 309 



During this time it is to be found hawking for insects over any 

 body of water with other swallows and flocking to the lowlands 

 to roost. 



It breeds not far to the north but has never been found nest- 

 ing in this county. 



RIPARIA RIPARIA (Linn.). Bank Swallow. 

 Common summer resident. 



The Bank Swallow arrives during the last half of April and 

 leaves in the first and second weeks of September. It may be 

 found in migration about any suitable feeding place in the 

 company of other swallows but in the breeding season is found 

 only near the Missouri River. Great numbers breed in colonies 

 in the high sandy banks of the river and in the exposed faces of 

 the deep deposits of loess along the bluffs. Several railroad cuts 

 at the base of the bluffs afford suitable sites for their nesting 

 burrows. 



This swallow may be distinguished from the Rough-wing, in 

 whose company it is often found, by the dusky throat band. 

 The Rough-wing has a dusky patch that is not clearly defined 

 by the unmarked throat. 



STELGIDOPTERYX SERRIPENNIS (Audubon). Rough-winged Swal- 

 low. 

 Common summer resident. 



The Rough-wing arrives sometimes as early as April 4th but 

 more often near the 15th or 20th and is present until late Sep- 

 tember. It is more widely distributed in this county in summer 

 than the Bank Swallow though it has much the same nesting 

 habits. It breeds in crevices in masonry, particularly in bridges 

 but also in clay banks, but never in large colonies like those of 

 the Bank Swallow, nor in such deep burrows. 



It has been seen feeding about the Swope Park lakes during 

 summer and no doubt nests in the park. 



Family BOMBYCILLIDAE. Waxwings. 



BOMBYCILLA GARRULA (Linn.). Bohemian Waxwing. 

 Very rare and irregular winter visitant. 



Only three specimens of this rare and uncertain bird have 

 ever been taken in this vicinity: February 27, 1911, December
