Q4 NORTHERN FALL FLIGHT. 
had only known one or two species of ducks, find 
their numbers increased; and, also, are frequented 
by other kinds. The hooded merganser, woodduck 
and ringbill seek the running streams of wooded riv- 
ers and their tributaries; the bluebill, redhead and 
canvas-back open lakes and deep ponds of water, 
secluded from view; while the bluewinged teal, redleg 
mallard, spoonbill, black duck and pintail frequent 
sloughs, marshes and swamps, where they revel upon 
the wild rice, duck and pond weed and frogbit. 
These little flights occur in all states, to a greater 
or less extent, until September; but a drifting always 
occurs north, south, east and west after that month, as 
food becomes scarce, water low or some other cause 
diverts the ducks’ movements.
