46 Wyoming Birds. 



ORDER XIV. COCCYGES. 



CUCULIDAE (Cuckoos, Anis, etc.), 



The Cuckoos are shy birds which seek the cover of dense foliage 

 in orchards, etc. Where they are abundant they are of great eco- 

 nomic value because of their habit of feeding upon caterpillars of 

 various kinds. They also eat beetles, grasshoppers, katydids, and 

 other insects. The charge that they are enemies to other birds is 

 unfounded. They are too rare in Wyoming to be of any economic 

 importance.

Up to 1902 but two observers reported this species. Since 

 then Walker is the only one who has secured specimens. 

 Peabody doubtfully records it. 



ALCEDINIDAE (Kingfishers). 



The Kingfishers feed almost entirely upon fish and must be re- 

 garded as detrimental from the economic standpoint.
