you may be sure it is that of the Red-eyed Vireo; the 
notes are clearly whistled, there is scarcely a suggestion 
of the overtone, they are pitched very high, and the 
groups themselves are closely connected—in fact, slurred. 
My rendering of the music shows that the bird attempts 
intervals of a third, fourth, fifth, and even an octave; 
but very few of these are really accurate; one has to 
presume more than half the time that the bird :.eant to 
do thus, or so, and take no note of failures. 
Warbling A smaller bird than the Red-eyed Vireo; 
oe the upper parts a dull olive-gray inclined 
treo gilvus : 
L. 5.75 inches toward brown; under parts dull white 
May 12th slightly dashed with pale yellow on the 
breast; the first primary wing feather exceedingly short, 
the long feathers of the wing and those of the tail tipped 
with olive at the edges; no wing-bars; a well-defined line 
of white-gray over the eye; the general color a grada- 
tion from gray on the head to olive-brown on the back. 
The pensile nest, usually attached to a Y branch well 
above one’s head, is woven of various vegetable fibres 
and lined with soft grasses. Egg white speckled slightly 
with umber, red-brown, or sepia. The range of this 
Vireo extends throughout North America. 
This familiar bird may be justly termed a village 
character. He makes his home among the maples and 
elms of Plymouth, N. H.;and Cambridge, as well as subur- 
ban New York knows his cheery song throughout May 
and June. Unfortunately he is not as easily seen as 
heard. His time is spent among the tree-tops exploring 
every leaf and twig with tireless energy; the best way to 
find him is to be on the lookout for a group of agitated, 
wagging leaves; there in the midst of the disturbance 
a tiny, restless, busy figure will presently appear and
