Semi-Pensile, Pensile or Hanging Nests 
focus the camera and give a time exposure without disturbing the 
bird, even though the camera was within three feet of the nest. 
They become highly indignant if the nest is touched, coming 
almost to one’s hand while they alternately scold and sing. 
The irregular song, which is delivered with great energy, is par- 
ticularly sweet and of surprising volume for so small a bird. 
The breeding season in the neighbourhood of New York be- 
gins about the third week in May. 
68la. Key West Vireo: V.n. maynardi (Brewst.) 
Closely resembling the preceding, it is rather smaller and 
lighter in colour. 
Range—Southern Florida. 
Nest and eggs described as being identical with those of the 
white-eyed vireo. 
648. Parula, or Blue yellow-back Warbler: Compsothly- 
pis americana (Linn.) 
Adult 6 —Upper parts gray blue, with a yellowish green patch in 
the middle of the back ; throat and breast yellow, with a 
dark brown or black patch ; sides rufous ; belly white. 
Adult? —Very similar, sometimes lacking the rufous colour on 
the sides. Length—4.73. 
Breeding Range—Locally throughout the Eastern States where 
the usnea moss is found. 
The nest is placed within tufts of hanging moss (usnea) ; it 
is perhaps more strictly speaking globular than pensile, as the 
entrance is often at the side ; it is usually at a distance of from 
‘‘three to forty feet” from the ground, and may be found in trees 
or bushes. The eggs, 4 to5 in number, are white, speckled 
with various shades of light reddish brown and lilac, chiefly at 
the larger end. Size—.67 x .49. 
It is in the swampy woods where on the trees and bushes 
the grey moss hangs in graceful festoons that the Parula makes his 
summer home; the nest being completed towards the end of May. 
748. Golden-crowned Kinglet: Regulus satrapa Licht. 
Adult 8 —Upper parts olive green, crown orange bordered by black; 
an undefined whitish line over the eye; under parts whitish.
