Nesting op Vireo olivaceds. — Mr. W. L. Collins, of Frankford, 
Philadelphia, Pa., writes : “ Whilst walking in a grove I found a nest of 
this species, upon which the female was sitting, although the framework 
was barely completed. Watching awhile, I presently saw the male fly to 
the nest with some soft substance in his bill, which he gave to his mate 
to arrange on the nest while he went in search of more. On then looking 
into the nest, I was surprised to find that it contained three eggs. Three 
or four days afterward, I again visited the spot, and found that the struc- 
ture had been completed in the interval. Thus the female had begun to 
lay some time before the nest was ready lor the reception oi eggs. — —

135. Red-eyed Vireo. Common. This little 
songster does not inhabit any particular local- 
ity.' It is a great benefit to the farmer in the 
way of insect destroying, and is constantly 
busy in this useful employment. The nest is 
hung from a crotch at the end of a branch and 
i is composed outwardly of the inner bark of 
trees, paper, cobwebs, etc. It is lined with 
pine needles and is deeply hollowed. The 
eggs, four to five ip number, are of a pure 
white, with a rosy tinge, and .sprinkled with 
brown, mostly at the largest end. "■

In the November number, Mr. F. H. Carpen- 
ter stated that the Red-eyed Vireo generally 
lays four eggs to a set. In my collecting In 
Dane County, Wis., I have examined many 
nests of this species, and very seldom four eggs 
in a set. Most of the nests contained three 
eggs, and two was by no means an uncommon 
number.

11. Vireo ollvaceM. Red-eyed Vireo. My 
observations on the family Vireonidae in this 
connection were made as thorough and com- 
plete as possible, and they at once show that 
in this family are the Cowbird’s greatest vic- 
tims. No birdsj when burdened with a Cow- 
bird’s eggs, are more helpless than the Vireos. 
Of the Red-eyed Vireo I have found six 
nests, and out of this number four contained 
eggs of the On wbird and the other two incom- 
plete sets. I have never found over four eggs 
of this Vireo in the same nest and this num- 
ber but once, as the usual number, when they 
contain Cowbird’s eggs, is one, two or three. I 
do not fully understand why this is the case, 
or whether or not it is caused by the Cowbird’s 
eggs being deposited.
