terials ; intending to take this with me on my return I hung it in 
the tree, but when I came back I found it on the ground, it was 
again hung as before, and again thrown down, although it had 
been firmly attached to a twig; this happened several times so 
that there was little doubt that it was the vireo’s doing, but why? 
I cannot imagine. On June 13th, the vireo began to sit on her 
four eggs; I shot her and found her to correspond exactly with 
Coues’ description of pila delphicus, except that the yellow on the 
breast was quite bright; the eggs closely resembled those of the 
red-eyed vireo, but were destroyed by an unfortunate accident 
before they were accurately measured. (Zhompson-Seton.) At 
Crescent Lake, Assa., June 11th, 1901, I found the nest and four 
eggs of this species ; nest of fine strips of bark, grass and fine 
roots, built in a poplar tree; at Long Lake, Manitoba, on June 
12th, 1894, I found a nest and four eggs of this species suspended 
to the branch of a willow six feet from the ground. (W. Razne.)

Vireo gilvus (ViEILL.) Bonar. ‘1838. 
A common summer resident at Halifax, N.S. (Dowzs.) Not 
uncommon at Calais on the boundary of New Brunswick. 
(Chamberlain.) A rare visitant in summer at Quebec. (Dionne.) 
A scarce transient visitant at Montreal; I have met with only two 
specimens of this species which I took on Montreal Island. (W2nile.) 
An abundant summer resident around Ottawa. ( Ottawa Natura- 
fist, Vol. V.) A common summer resident, nesting high up in 
maple and elm trees in eastern Ontario. (Rev. C. J. Young.) I 
have taken this species several times at Emsdale, Muskoka dis- 
trict in May; Mr. Tavernier has taken the species at Beaumaris, 
Muskoka. (/. H. Fleming.) Abundant along the city streets in 
London, Ont.; but somewhat less so in the country; eggs usually 
four, but sometimes only three, nests always high up, not less 
than 25 feet from the ground, while the red-eyed vireo seldom 
builds higher than eight feet and usually less; the male bird takes 
his share of the work of incubating and sings freely while sitting.
