bird, though the eggs of both species are much similar. The scolding 
notes of this bird soon brought her mate upon the scene, but he 
seemed more disposed to sport with her than assist to drive off the 
intruder. Both birds, however, came quite close, and I identified 
them as a pair of the black-throated blue warbler species. Being 
anxious to secure this nest and a full set of eggs, I noted the place 
and returned four days later. Then the female was seated on the 
nest, and when she flushed off I found that it contained three of her 
own eggs and one of a cowbird. These I collected and prepared for 
my cabinet, but they have since passed to the collection of a gentle- 
man in Philadelphia. After I had secured the nest and eggs above 
described, on my homeward way, I found another nest of the same 
species. This was also placed in the fork of a small maple twig, 
about two feet off the ground, and on the outskirts of a thick patch 
of low underwood, and then contained three young of the bird’s own 
two or three days old, and also a young of the cowbird. I noted in 
both cases that the old birds on leaving the nests dropped to the 
ground and made quite a commotion among the dry leaves, evidently 
with the intention of diverting attention from the nests. (W. ZL.
