Maine (Lake Umbagog. 
Three specimens taken. The first June 3, the 
second June 4, the third June 5. The first vms shot 
in the top of a tall beech; the second in a thicket of 
firs; the third in a small birch surrounded by firs. 
All throe specimens v;-ore females. We thought that one 
of them uttered a faint vmrbler-like chirp, but other- 
v/iso they v/ere perfectly silent. 
Three shot on the Tyler Path. They v/ere in a 
mixed flock of Warblers, Titmice, etc., in lov; second 
gro\7th birch and maple. They \Yero very tame, perfectly 
silent, and more active in motions that the other Viroos 
quite as much so indeed as any of the Warblers. Tv;o 
of them when picked up still hold in their bills largo 
green caterpillars. All ^vere males and one I think an 
adult. 
Shot a young female in the same place v/here those 
Y/ere taken the 29th. 
Shot one in perfect fall plumage; it v/as in the 
top of a high beech, in a large mixed flock. 
Shot a male among small vald cherry trees on the 
edge of the v/'oods. It kept low dov/n and vras silent. 
Tv;o specimens killed. 
A Viroo hoard singing to-day was probably of this 
species, its song was most like that of the Red-eyed but

Red-eye but I failed to secure it.

I heard only tY^o notes, a soft tender pseuo , similar to 
that of the Red-eyed Viroo v/hen mating, and a harsh petu¬ 
lant cry exactly like that of the Warbling Vireo. ’This 
species is scarce distinguishable in motion and appear¬
