FURTHER NOTES ON THE PHILADELPHIA VIREO, 
WITH DESCRIPTION OF THE NEST AND EGGS. 
BY WILLIAM BREWSTER. 
Plate XI 
In the ‘Bulletin of the Nuttall Ornithological Club’ for Janu- 
ary, 1880, I published some 1 Notes on the Habits and Distribution 
of the Philadelphia Vireo ( Vireo philadelphicus ).’ 1 his article 
was followed in 1897 by Dr. Dwight’s ‘A Study of the Philadel- 
phia Vireo ( Vireo philadelphicus) ,’ which gives by far the fullest 
and best account of the bird’s habits, and especially of its song, 
that has ever appeared. Of its breeding habits we still know very 
little. “On the 9th of June, 1884, while camped near Duck 
Mountain,” Manitoba, Mr. Seton found a nest which “was hung 
from a forked twig about eight feet from the ground, in a willow 
which was the reverse of dense, as it grew in the shade of a pop- 
lar grove. The nest was pensile, as usual with the genus, formed 
of fine grass and birch bark. The eggs were four in number, 
and presented no obvious difference from those of the Red-eyed 
Vireo, but unfortunately they were destroyed by an accident before 
they were measured .... The bird on being shot answered per- 
fectly to Coues’s description, except that on the breast it was of 
a much brighter yellow than I was led to expect.” (Ernest E. 1 . 
Seton, Auk, II, 1885, pp. 305, 306). The identification of this 
nest must be accepted, of course, as wholly satisfactory, but that of 
Philadelphia Vireo ( Vireosylva Philadelphia) in Massachusetts in 
Autumn. — On Sept. 5 , 1915 , I shot a young male Philadelphia Vireo in 
Harvard, Mass. The specimen is now in my collection (No. 551 ). 
I am indebted to Mr. Outram Bangs of the Museum of Comparative 
Zoology for verifying my identification. — James L. Peters, Harvard, 
Mass.
