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. 
Tt 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 BomBycruuipan. 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
