 Nu CvY5 Adult with Caterpillar in Bill on Perch with Young Bird. 

 Ithaca. (June 10, 1915) Allen 



The old bird has brought a tent caterpillar for the young bird, 

 the cuckoo being one of the few birds that destroy this pest. 

 Different from most young birds, the cuckoo after leaving the 

 nest makes no show of excitement when the old birds come with 

 food. Note the shape of the bill and the arrangement of toes.

 open. 



Dove, Mourning (Zenaidura macroura carolinensis) 



The mourning dove is the only wild pigeon found in New York 

 State today. This bird is a relative of the extinct passenger 

 pigeon, which it resembles closely. It feeds upon grain and 

 weed seeds. The name is given it because of its weird and 

 mournful call. 11-13
