I 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, 780 (Small). 
A small colony was at Vale Summit June 5 to 14, 795. 
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 isabundant. 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.
