well-known concerted drive for fish into shallow water. This 

 was observed at Goose Island in the Missouri River a short 

 distance above the city. 



Hunters only too often bring in specimens of Pelicans wan- 

 tonly destroyed for " sport." Among these have been noted 

 males, taken in the autumn, with the nuptial horn or mandible 

 keel still retained. This temporary appendage is usually cast 

 on the breeding ground before the southward flight begins. 



Favorable localities, where they may rest and feed in seclu- 

 sion, or where they are protected, have been known to harbor 

 great numbers of these migrants for days and even weeks at 

 a time. One lake in this district is visited twice a year by a 

 flock of from 100 to 1,500 Pelicans. They sometimes remain 

 on this pond for two weeks. 



Order ANSERES. Lamellirostral Swimmers. 



Family ANATIDAE. Ducks, Greese and Swans. 



Subfamily Merginae. Mergansers. 



MERGUS AMERICANUS Oassin. Merganser. 



Not uncommon migrant; occasional winter resident. 



Mergansers arrive late from the north, usually during the 

 last half of November, and leave early, in some seasons as early 

 as February, but more often in March and early April. 



During the winter of 1910-1911 a flock of six were observed 

 during the entire winter at the mouth of the Big Blue. Again 

 in 1916 another larger flock wintered on a nearby pond, leav- 

 ing early in March. 



MERGUS SERRATOR Linn. Red-breasted Merganser. 

 Rare migrant. 



This duck is occasionally seen in hunters' bags and is prob- 

 ably more often taken than the records indicate. Two beauti- 

 ful specimens were examined in a gunner's string on March 

 18, 1916, on the Missouri River near Sugar Creek. There are 

 a half dozen authentic records for the last few years. 



LOPHODYTES CUCULLATUS (Linn.). Hooded Merganser. 



Common migrant and formerly a not uncommon summer resident. 



This striking duck is regularly taken by hunters on the river 

 and at the many shooting resorts in this vicinity.
