SINGING BIRDS.

tic, more than 100 feet from the ground. At other times they 
are not more than 50 to 70 feet high. The only nest I have 
been able to examine was made . externally of flat and dry 
sedge-grass blades, for which, as I have observed, are occa- 
sionally substituted strings of bass. These dry blades and 
strips are confined and tied into the usual circular form by 
caterpillars’ silk, blended with bits of wool, silk-weed lint, and 
an accidental and sparing mixture of vernal grass tops and old 
apple-blossoms. It was then very neatly lined with the small 
flat blades of the meadow grass called Poa compressa. 
This species is rather uncommon in the Maritime Provinces 
excepting near the Maine border in New Brunswick, and in the 
more southern portions of Nova Scotia. It is fairly common in 
southern Quebec, and abundant in Ontario. In the New England 
and Middle States it is an abundant summer resident. At the West 
it ranges north to the fur countries. 
RED-EYED VIREO. 
ViREO OLIVACEOUS. 
Char. Above, bright olive, crown ashy ; beneath, white faintly tinged 
with dull olive on sides ; wings and tail dusky. Length to 614 
inches. 
Nest. In an open pasture or along margin of field ; suspended from 
fork of an upper branch ; composed of grass and vegetable fibre, and 
lined with fine grass, etc. 
Eggs. 3-5 ; white (sometimes with a faint pink tint) spotted sparingly, 
around larger end, with dull brown ; 0.80 X 0.55. 
These common and indefatigable songsters appear to inhabit 
every part of the American continent, from Labrador to the 
large tropical islands of Jamaica and St. Domingo ; they are 
likewise resident in the mild tableland of Mexico. Those 
individuals who pass the summer with us, however, migrate to 
the warmer regions at the commencement of winter, as none 
are found at that season within the limits of the United States. 
The Red-Eyed Vireo arrives in Pennsylvania late in April, and 
in New England about the beginning of May. It inhabits the
