he sat facing the south-east and the sunlight, striking
full on his throat and breast, brought out clearly
the yellowish coloring of those parts which was of somewhat
unusual depth and extent for a Vireo philadelphicus in
spring plumage. Had I not been able to see him thus
plainly, as well as to note his small size (he looked
no bigger than a Nashville Warbler) when he crossed the 
road, I should now have concluded that he was
nothing, after all, but a common Red-eye for during
the entire time that he remained in the top of 
this tallest tree he poured out a flood of song not
less rapid, varied, continuous and emphatic than, and,
in every respect, as far as my ears could detect, identical with
that of the most voluble "Preacher". Even the characteristic
ser-wee-e was wholly omitted. But when, after this brief
period of relaxation, he returned to the nest he resumed
the slow, broken, listless singing which I have already
described & with it the ser-wee-e note. Another bird
evidently of the same species, was singing all the while in
a precisely similar manner about sixty yards back from
the road in the direction of the Lake. I did not
go in search of him. partly because the bushes were very
wet but chiefly for the reason that I was deeply engrossed 
in the bird whose nest I had just found.

  I spent the greater part of the forenoon (from 9 to 12,
with the exception of about fifteen minutes devoted to going
back to the house to get Gilbert) in the immediate
neighborhood of the nest. Save during the brief period which
the male spent in the tall aspen (and possibly that during which
I was absent) he remained on the nest singing practically
the whole time. He seemed restless & ill at ease frequently
