A nest of the Red-eyed Vireo, containing three eggs 
of the rightful owner and one of the Cow-bird was found 
(by Gilbert) in an apple-tree in our orchard on June 8, 
When I next looked into it on June 17th, it held a young 
Red-eyed 
Cow-bird, newly hatched, and the three Vireo eggs. To-day 
Vireo 
(at 2 P. M,) there were two young Vireos, an unhatched 
hatCheB 2 
Vireo’s egg, and the young Cow-bird. A few years ago a 
of her young: 
Red-eyed Vireo not only hatched but reared two or three 
besides a 
of her own young besides a young Cow-bird, in a nest in 
Cow-bird 
this orchard, I wonder if this will be repeated. The 
instance just referred to is the only one that has ever 
come under my notice where any young of the rightful 
parent were reared with a young Cow-bird. 
White-bellied Swallows are noY/ feeding young almost 
wholly fledged in tviro boxes at the Farm and two on the 
White-bellied 
Ritchie place. Both sexes share this labor equally, and 
Swallows 
keep at it steadily from morning to night, one or the 
feeding 
other coming to the box every two or three minutes. As a 
young 
• 
rule, they go no further from it than fifty to one hundred 
yaxds, hawking for insects just above the tops of the trees 
in and about the garden and orchard. The grace and 
1 * 
precision, with which the bird alights just 
below the hole,with its wide-spread tail pressed against 
the front of the box and its feet clinging to the lower 
rim of the hole,are admirable to wa.tch.
