230 Trans. Acad. Sct. of St. Louis. 
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 ANATIDAR. Ducks, Geese and Swans. 
Subfamily Merginae. Mergansers. 
MERGUS AMERICANUS Cassin. 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.
