Clivicola riparia (616). Bank Swallow. 



Common summer resident. Quite a number were at Loch 

 Raven on April 14 ('95), but they were down the necks earlier, 

 for on April 19 ('95, Fisher), at Gunpowder, a new hole had 

 been dug about a foot deep and two others a few inches. The last 

 birds were noted September 12 ('85, Resler). At Washington, 

 from April 25 ('86, '94) to September 15 ('90, Richmond). 

 On July 17, '91, a large number, possibly between 3000 and 

 4000 were on a ducking blind at the mouth of Back River ; 

 they kept up an incessant twitter and w^ere evidently ready to 

 leave for their winter home. May 12 ('91), slightly incubated 

 eggs, and July 17 ('92), young birds, are extreme nesting dates. 

 Sets are 3 of 2, 2 of 3, 3 of 4, 3 of 5, 2 of 6, and 2 of 7. 



Stelgidopteryx serripennis (617). Rough-winged Swallow. 



Summer resident, but not as numerous as the Bank Swallow. 

 Observed at Washington April 8 ('92, R. Ridgway, Auk, ix, 

 307), at Baltimore, April 19 ('79, Resler) ; the last recorded at 

 Washington was shot on September 3 ('94, Richmond). Sets of 

 eggs, noted from May 13 ('83) to June 15 ('84), are 2 of 4, 1 

 of 5, 1 of 6, and 1 of 7. " Numbers of these birds breed along 

 the Potomac River in crevices of the rock; ... a nest of 

 7 eggs found during June, '87, contained six eggs of this 

 species and one of the Barn Swallow" (C. W. Richmond, Auk, 

 V. 23). At Hagerstown, Small says ('80-'81), "the Bank 

 and Rough-winged Swallows are about equally common." 



Family Ampelid^ — Waxwings. 



Ampelis cedrorum (619). Cedar Waxwing. 



Resident, roving in flocks all the year, from which, in their 

 leisurely manner, a pair will detach themselves and go to house- 

 keeping, generally in July or August. Eggs are noted from 

 June 17 ('92, Blogg) to August 21 ('92). At Vale Summit 

 a nest had 5 fresh eggs on June 11 ('95). Sets are 1 of 3, 

 2 of 4, and 4 of 5.
