for 75 percent of the recoveries, it is difficult to compare the 
migration pattern with that of stations to the north. The fact that 
90 percent of all New Brunswick recoveries were taken the same fall 
as banded indicates an unusually heavy early kill. The recoveries 
from the New Brunswick bandings end in the Delaware-New Jersey area 
for the most part, although there is one record for Florida. 
It is anticipated that more extensive bandings will be 
undertaken during the coming years in the Maritime Provinces which 
will shed more light on the extent of movement of locally raised 
black ducks. Since Nova Scotia supports a fair wintering population 
in some years, it is possible that banding, at least on the southern 
tidal marshes, may not show the true extent of migration. This condi- 
tion is discussed further in connection with Massachusetts bandings. 
Maine 
Bandings have been carried on at several points in eastern 
Maine, beginning in the early twenties. Recoveries total 298. The 
most important location has been the Penobscot Valley, where in recent 
years the Maine Cooperative Wildlife Research Unit has embarked on an 
expanded banding program. Limited and scattered banding has been done 
on tidal areas, but the greater portion has been on fresh water, usually 
within 50 or 60 miles of the coast. Only with the Penobscot River band~ 
ings were significant numbers of blacks banded before the shooting season. 
Records from this station make up about two-thirds (188) of all the 
recoveries. The plotted direct recoveries from the Penobscot River 
station (totaling 109) show an interesting pattern which conforms remark- 
ably with the strong coastal migration pattern exhibited by the blacks 
from eastern Quebec and Labrador. The mapped recoveries (fig. 4) in- 
dicate that these birds probably migrate down the Penobscot Valley to 
the coast, then follow the coastal habitat most of the way to the south- 
ern wintering areas. The southernmost recovery point is South Carolina 
and approximately 48 percent of the records are from Long Island south. 
If we exclude Long Island, we still have 39 percent of the recoveries 
occurring from New Jersey south. Here again New Jersey takes a signif- 
icant percentage, 16 percent. 
The kill, within a 50-mile radius of the Penobscot River 
station, counted for about 21 percent of the recoveries. This is not 
excessive in comparison with other stations farther south along the 
coast. The 62 indirect recoveries, with 45 percent or 28 recoveries 
from Long Island south, reflect the pattern of the direct recoveries. 
Details of the southern distribution of indirect recoveries 
differ somewhat from the directs. Maryland rather than New Jersey 
accounts for the greatest number of indirect recoveries, the number 
being 11 percent. Only 8 percent of the indirect recoveries were taken 
within a 50-mile radius of the station. Of the New England states, 
Massachusetts leads with 13 percent. Among the indirect recoveries, 
the southernmost record is from Florida.
