20 WyYyoMING BIRDS. 
70. Sterna hirundo: Common Tern. 
Blackwelder in the Teton region saw what he judged to be 
this bird. This is our only record other than that in 1902 
by Knight. 
77. WHydrochelidon nigra surinamensis: Black Tern. 
The records of this bird are from Cody, Sheridan, Lake 
Como, Cheyenne and Douglas. 
ORDER IV. STEGANOPODES. 
PHALACROCORACIDAE (Cormorants). 
From the economic standpoint the Cormorants in Wyoming are 
of no importance. They feed upon fish. 
119. Phalacrocorax carbo: Cormorant. 
“Probably accidental. There is but one recorded for Wyo- 
ming and that is from Bond of Cheyenne.” (Knight.) 
120. Phalacrocorax auritus auritus: Double-crested Cormorant. 
There are but three Wyoming records, two from the Lar- 
amie Plains and one from near Buffalo. See Lockwood 
and Knight. 
PELECANIDAE (Pelicans). 
The Pelican feeds upon fish and, what is more serious, it is 
said to spread disease among the fish of the lakes in and near the 
Yellowstone Park.
