PELICANS. 



125. Pelecanus erythrorhynchos Gmel. 



American White Pelican. 



Resident, rare; migratory, common. In late spring this 

 species usually visits the large ponds and sub-alpine lakes and 

 breeds in a few localities. Dr. Grinnell in a private letter to me 

 states that he found several fledglings on the Medicine Bow 

 river about the year 1881 ; he also reports them from the Yel- 

 lowstone lake, 1875. Bond reports them from Cheyenne; Dr. 

 Jesurun from Douglas. Several have been killed at Hutton's 

 lake, Albany county, and I have seen large flocks about these 

 lakes several times in late spring. 



126. Pelecanus occidentalis Linn. 



Brown Pelican, 

 Accidental. A single specimen has been taken by Bond 

 at Cheyenne and is now in the high school collection in Chey- 

 enne. 



DUCKS, GEESE AND SWANS. 



129. Merganser americanus (Cass.). 

 American Merganser, 

 Summer resident; common. This bird is usually called 

 a "fish duck" or "saw bill." It breeds along nearly all the 

 streams in the state below 8,000 feet. Flesh unfit for food, 

 since they feed almost entirely upon fish. Reported common 

 by Bond, Jesurun and Coues. Williston reports it from Como 

 lake ; Allen from Fort Fred Steele ; Grinnell reports the young 

 unable to fly on Yellowstone lake in August, 1875. The Uni- 

 versity records are as follows: Hutton's lake; Clear creek, 

 Johnson county ; Grey Bull river, Big Horn county ; and Green 

 river, Uinta county. Hayden, 1870, reports specimens from 

 Fort Bridger and Sweetwater river.
