ROUGH-WINGED SWALLOW. 403 



ROUGH-WINGED SWALLOW. 



Stelgidopteryx serripennis. 



Char. Above, grayish brown; beneath, brownish gray, whitening on 

 the belly. Edge of wings rough to the touch. Length 5 to 5ji( inches. 



A^est. 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. 



Eggs. 4-7 ; white; 0.75 X 0.50. 



We are indebted to Audubon for the discovery of this spe- 

 cies so much aUied to the preceding, who first observed it 

 near Bayou Sara, and afterwards in South CaroUna. 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 {P etrochelidon fulva) 

 and the Bahama Swallow {Calichelidon cyaneovirides) 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.
