1 saw quite a number on the telegraph wires, young and old, 

 ready to go south. Sets are 1 of 1, 1 of 2, 2 of 3, 1 of 4, 1 

 of 5. 



Chelidon erythrogaster (613). Barn Swallow. 



This, our swallow proper, is an exceedingly numerous sum- 

 mer resident, there being scarcely a barn or out-building that 

 has not its swallow nests on the rafters. First noted on April 

 3 ('80, Resler), on the 15th ( ? 93) they were numerous, remaining 

 so until September 20 ('90, Resler). Birds congregated on the 

 telegraph wires, ready to migrate, have been seen as early as 

 July 5 ('94). Nesting dates range from May 29 ('81), slightly 

 incubated eggs, to August 9 ('93), small young birds. Sets 

 are 1 of 1, 4 of 3, 6 of 4, and 10 of 5. At Washington they 

 were noted March 30 ('90), and nests with 1 and 2 eggs were 

 found on May 16 ('86, Richmond). At Hagerstown on March 

 20, '80 (Small). 



A small colony was at Vale Summit June 5 to 14, '95. 



Tachycineta bicolor (614). Tree Swallow. 



Sparingly distributed along the shores of tidewater Maryland 

 in summer, this species may be seen anywhere during migra- 

 tions, when it is abundant. Noted from March 30 ('92, Resler) 

 to October 17 ('94, Resler); quite a large number were flying 

 south in a loose, desultory manner over Ferry Bar on August 

 12 ('95). At Washington it is recorded from " March 30 ('90), 

 to October 14 ('94), when there must have been a wave of them, 

 as Wm. Palmer got one and saw several at Kensington, Md.; 

 Geo. Marshall saw one at Laurel, Md., and R. Ridgway saw 



2 or 3 at Gainesville, Va." (Richmond). On October 14 ; 

 '94, there was quite a large number in Dulaney's Valley. 

 Several were seen at Harper's Ferry, April 8, '87, by F. L. 

 Washburn (Birds Vas., 77). At Hagerstown in September, 

 '82, and May, '83 (Small). Nests with eggs are noted from 

 May 12 ('94, Fisher) to July 3 ('93, Blogg). Sets are 1 of 4, 

 2 of 5, and 1 of 6.
