with 6 well incubated eggs was found, and on June 14,785, 
and June 5, ’87, nests with 5 young about half grown were 
also found (C. W. Richmond, Auk, v, 23-4). 
Helminthophila pinus (641). Blue-winged Warbler. 
This species, fairly numerous in migrations, from May 5 
(95) to May 16 (793, Wholey), and from August 18 (91, Gray) 
to September 21 (’94), has been found as a regular, but rare 
summer resident along Gwynn’s Falls, between Calverton and 
Franklin (Blogg and Gray), where in 792, on June 11.and 14, 
young birds just out of the nest were noted, and on the latter 
date 3 were caught. On July 5, another brood had just 
left a nest. In ’93, on May 20, a nest was half built; on the 
27th it contained one egg, but later it was deserted. On June 
13 a nest was found containing 3 birds just hatched and 
an infertile egg; on July 1, another had 4 birds under a 
week old and an infertile egg, and on July 12, another nest 
was found with young birds. On May 29, ’94, a nest was 
found with four fresh eggs. 
On June 15, ’95 (Fisher) a pair was seen at Mt. Washington 
where five days later I noted a pair feeding young, and on July 
10, 791 (Fisher), one bird secured from a flock of 5 or 6 at 
Ruxton indicates its nesting there. ‘Geo. Marshall and others 
have found it breeding at Laurel, Md., and at Washington, 
where it is rare as a breeding bird, a nest was found by Mr. H. 
H. Birney early in June, ’80, with 4 eggs about to hatch” 
(Richmond). 
Helminthophila leucobronchialis (—). Brewster’s Warbler. 
The identity of this bird is not very clear, but it is supposed 
to be a hybrid ; it has been found from Virginia to Connecticut, 
and as far west as Michigan. On May 15, ’85, one was taken 
near Fort Myer, Alexandria County, Va., by Wm. Palmer 
(Auk, ii, 304), and a very typical male was taken at Beltsville 
on May 1, ’95, by A. H. Thayer (C. W. Richmond, Auk, xii, 
307).
