below the built-up part of the City of Philadelphia. 
It was flying in company with a flock of rusty 
Gracle; the specimen is now in the Academy of 
Natural Sciences. 
Coccygus Americanus.—Bonap. 
Yellow-billed Cuckoo. 
This bird is very plenty in some parts of the 
country I have found it more abundant in New 
Jersey and Pennsylvania than in any other States. 
I have met with it as far west as Iowa, but it is 
rare in that section; it breeds in Iowa and the 
above States. 
Coccygus Exythrophthalmus—Bp. 
Black-billed Cuckoo. 
The Black-billed Cuckoo is very common in 
Iowa and all the Eastern States. It breeds in all 
of them; the nest is very slightly made of moss 
and sticks, and it does not look strong enough 
to hold the bird. It is noted for sucking and 
destroying other birds eggs. Ihave never found 
more than two eggs in one nest. 
Campephilus Principalis —Gray. 
Ivory-billed Woodpecker. 
I have never found but one specimen of this 
bird, as it is very shy and hard to approach. 
I found this in South Carolina. It is very plenty 
in Texas, where it breeds.
