ROUGH-WINGED SWALLOW. 
Stelgidoptervx serripennis. 
Char. Above, grayish brown; beneath, brownish gray, whitening on 
the belly. Edge of wings rough to the touch. Length 5 to 5^ inches. 
Nest. In a cavity of a bank or in a crevice of a stone wall or bridge, 
usually near a stream ; made of dry grass lined with feathers. 
4-7 : white ; 0.75 X 0.50. 
We are indebted to Audubon for the discovery of this spe- 
cies so much allied to the preceding, who first observed it 
near Bayou Sara, and afterwards in South Carolina. Of its 
habits he says nothing ; but it is rarer, and he thinks its 
habitual residence may prove to be far to the westward, — 
perhaps the valleys of the Columbia. 
This species is more common in the Western Faunal Province 
than in the East; it is abundant in British Columbia. It occurs 
regularly, however, throughout the Eastern States north to New 
York, Ohio, and Illinois, and sparingly in Connecticut. It has also 
been found in parts of Ontario. 
In appearance and habits it so closely resembles the Bank Swal- 
low that it may be overlooked by the casual observer ; it does not, 
however, confine its choice of a nesting site to a sand-bank, but 
will place its nest amid the stones of a wall or bridge, in a crevice 
of a building, or even in a knot-hole. 
Note. — The Cuban Cliff Swallow {Petrochelidon fnlvd) 
and the Bahama Swallow {Calichelidon cyanecvirtdes) have 
been added to the United States fauna by Mr. W. E. D. Scott, who 
captured examples on Dry Tortugas island during March and 
April, 1890.
