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 were 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 AMPELIDJE 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.
