40 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.
