A Preliminary List of the Birds of 

 Wyoming, With Notes. 



GREBES. 



This family includes many species of expert divers. Us- 

 ually they are called "hell divers" by hunters. They feed upon 

 snails and insects and also upon fish. They are harmless and 

 their flesh is not valued for food. There is but one species of 

 Grebe that breeds abundantly in this state, and this is found 

 in large numbers about ponds varying from 4,000 to 8,000 feet 

 above the sea level. 



1. .ffichmophorus occidentalis (Lawr.). 



Western Grebe. 



Migratory; rare. Thus far this species has been found 

 only in southeastern Wyoming ; but should be found in greater 

 abundance in the southwestern counties. Mr. Bond has mount- 

 ed one specimen for the Cheyenne high school and has also 

 observed others during autumn months in the lakes near Chey- 

 enne. Dr. Jesurun took one of these birds at Douglas on Oct. 

 13, 1897. 



2. Colymbus holboellii (Rienh.). 



Holboell's Grebe. 

 Migratory ; rare. Dr. Jesurun of Douglas has one speci- 

 men taken Oct. 18, 1893 and Mr. Bond has mounted one for 

 the Cheyenne high school collection. Mr. Bond has seen sev- 

 eral others on the lakes at Cheyenne.
