372 | BIRDS—TYRANNIDA. 
Mr. Kirkpatrick in his series of articles in the Ohio Farmer, 1860. Mr. 
Langdon, in 1877, gives it as a “rare migrant in spring,” but in his Re- 
vised List gives it as “doubtfully identified.” 
The Olive-sided Flycatcher is much more common west than ope of 
the Mississippi. Numerous instances of their breeding in New England 
are recorded. The nearest locality in which they are known to breed is ~ 
Lewis county, N. Y., where Mr. Merriam has taken the nest and finds 
the birds not uncommon. It appears to be more numerous in New Eng- 
land at present than formerly, but has not been found in many instances 
south of New York. The Olive-sided Flycatcher frequents coniferous 
woods, and the nest is usually placed in an evergreen tree. The eggs are 
creamy white, marked about the greater end with a confluent ring of 
purple, lavender, and brown spots, and much resemble, except in size, 
‘those of the next species. They measure .82 by .62. |

-Olivaceous brown, rather darker on the head, below with the sides washed with a 
paler shade of the same nearly or quite across the breast; the throat and belly whitish, 
more or less tinged with dull yellowish; under tail coverts the same, usually streaked 
with dusky; tail and wings blackish, the former unmarked, the inner quills edged and 
the coverts tipped with whitish; feet and upper mandible black, under mandible 
usually yellow, sometimes dusky. Spring specimens are purer olivaceous. Harly fall 
birds are brighter yellow below. In summer, before the now worn feathers are renewed, 
quite brown and dingy whitish. Very young birds have the wing-bars and pale edging 
of quills tinged with rusty, the feathers of the upper parts skirted, and the lower plum- 
age tinged with the same; but in any plumage the species may be known from all the 
birds of the following genus by these dimensions: Length, 6-64; wing, 34-34; tail, 
28-3; tarsus, middle toe and claw together hardly one inch, or evidently less; tarsus, 
about 4, not longer than the Dill. 
Habitat, Eastern United States and British Provinces, west to border of central 
plains. ‘South to New Grenada. Mexico. 
Abundant summer resident from May to September. Frequents for-
