CLAPPER wx, 
FALL MIGRATORY FLIGHT OF DUCKS NOT HATCHED 
IN THE UNITED: STATES. 
The various species of our Anatide, which have 
traversed the length of the great continent of North 
America and beyond, seeking places in which to 
raise their young on lonely islands, musquaids, lakes 
and swamps where straggling footsteps rarely intrude 
or desecrating hands are laid upon the millions of 
eggs scattered profusely on every side; where feathers 
and excrement are thickly strewed around, and the 
din of their cries, the rustle of their wings and the 
repeated roar of rising flocks echo and reécho from 
the cliffs and through the cafions of the adjacent main- 
land; now return with their young to a warmer clime, 
situated below the frost line, in latitude 34” to. 357, 
impelled by Nature’s great and unerring law. Their 
migratory propensities and peculiar straight, curved 
and wedge-shaped lines, which each peculiar species 
assumes under regular generalship, differ so from each 
other in shape, length, numbers and flight that in all 
countries they appear endowed with characteristic 
weather prophecy, as high in the air they shape their 
course, guided by unerring instinct to their southern 
goal. 
These migratory flights, whether during the spring 
or fall, differ widely from the local ones in shape, form, 
numbers, height and speed; they are easily recognized
