a little later (early November) the main migrations into the South and 
Middle Atlantic States get under way. The first of these migrations 
from Ontario, particularly to the South Atlantic States, are apparently 
2 to 3 weeks earlier than the flights from eastern or Maritime Canada 
and eastern Maine. As for the southwestern movement, the Ontario black 
ducks work their way south into Tennessee, Arkansas and northern Alabama 
during the second half of November and apparently do not reach the lower 
Mississippi and Gulf Coast until the first or middle part of December. 
These far southern records probably represent a gradual migration as 
well as relatively loug direct flights from the northern states. 
The data for Seney and Munuscong on the Upper Peninsula of 
Michigan have been recorded separately in figures 29 and 30. Perhaps 
these two stations might logically be combined but the difference in 
trend and time of movement would seem to warrant separation, at least 
from an academic point of view. 
The early fall movements into the northern states is more 
noticeable with the Munuscong birds. These blacks move into the Lower 
Peninsula and into Wisconsin 10 days to 3 weeks in advance of the 
Seney population. This is remarkable in that some of the Munuscong 
blacks on their way west to Wisconsin, undoubtedly, pass near Seney. 
Some of the Seney blacks moving south and east through the Lower Penin- 
sula eventually overtake the Munuscong birds in Ohio (Lake Erie), but 
even here the main flight of the latter arrives about 10 days to two 
weeks ahead of the Seney birds which do not begin to increase in number 
until about the middle of November. In like manner the westerly move- 
ment through eastern Wisconsin arrives in force in Illinois by early 
October, keeping the 2 to 3 week'ts lead over the Seney blacks. 
Both populations apparently begin to leave the northern 
states for the lower Mississippi and Guif Coast States about the same 
time arriving in the southland around the middle of November. From 
the data it would seem that much of the Seney population skips over 
the intervening states of Kentucky and Tennessee, whereas these areas 
seem to be important stopping places for the Munuscong black ducks. 
At the same time these populations arrive in the Gulf Coast 
States, part of the Munuscong population is being taken also in the 
Middle Atlantic States, particularly Virginia. The invasion of the 
South Atlantic States probably starts about the same time, though the 
evidence is that most of them arrive in December with the peak for the 
Munuscong blacks about 10 days to 2 weeks ahead of the Seney birds. 
Figure 31 shows the distribution of a limited series from 
Orland Park, Illinois, banded in August, September, and early October. 
Although there is some early October drifting into Indiana and south- 
west through Illinois these blacks do not seem to exhibit any pro- 
nounced movements until early December. Black ducks from the Upper 
Peninsula of Michigan have been in the Southern states 2 to 3 weeks
