PHILADELPHIA VIREO. 
Family Vireonide.’ 
Philadelphia This is the smallest of our six Vireos. 
Mates ai One not acquainted with the eccentricities 
Ppiladtebphice of ornithology would naturally infer that a 
L. 4.80 inches Philadelphia Vireo is, or ought to be, a com- 
May 18th mon bird in the vicinity of the ‘‘ city of broth- 
erly love;’’but that is not the case, the bird, on the contrary, 
is rare indeed about Philadelphia and is distinctly boreal. 
It happened that the first known specimen was captured 
by a Mr. Cassin near this city in 1842, and was described 
by him nine years later; as for the breeding place, nest, 
and life habits, they were not discovered until 1884, 
apparently in Canada!* Hence it would seem logically 
proper that this species should have been named the Can- 
ada Vireo. But of course, a lost, strayed, or stolen polar 
bear discovered in Philadelphia is liable, in the other prem- 
ise, to be named Ursa philadelphica! Farther south than 
northern New England and New York this Vireo is a 
rare migrant. Its colors are quite different from those of 
the other species; upper parts light olive green, under parts 
distinctly washed with sulphur yellow, the breast yellow- 
est, crown gray, a whitish bar over the eye, a narrow, dark 
bar through it, cheek grayish, no wing-bars. Nest, pensile, 
woven with fine grasses, shreds of birch bark, etc., sus- 
pended at the fork of a branch about seven to ten feet from 
the ground. Egg, white sparingly flecked with umber 
brown especially about the largerend. This species breeds 
from Manitoba, Ontario, and Labrador south to New 
Brunswick, Maine, northern New Hampshire (possibly 
northern New York), and northern Michigan. It is com- 
mon on the woodland roads and clearings of the Umbagog 
region of Maine, and on those about Dixville Notch, less 
common on those of the Franconia Notch, and it is prob- 
ably a rare resident on those which flank the Presidential 
Range of the White Mountains, New Hampshire,—but 
there is no record to prove this last. 
The song of the Philadelphia Vireo has been likened to 
that of the Red-eye, but the resemblance is entirely super- 
ficial. The isolated groups of notes, unlike those of the
