Family CUCULI D^. Cuckoos, Anis,' etc. 



The family Cuculidae contains about 180 species from different 

 parts of the world, and of these 9 (including subspecies) occur in 

 North America. They are rather solitary birds and are rarely found 

 away from trees. Unlike the European species, the American 

 Cuckoos build their own nests, although occasionally their eggs are 

 found in the nests of other birds. Its peculiar note suggests its name, 

 and is a familiar sound to those who wander in the woods and fields. 

 They are of great value to the agriculturist, as besides other insects 

 they destroy immense numbers of caterpillars, including the Canker 

 Worm, and the Tent Caterpillar, Clisiocampa americana.
