stronger tie with the Middle Atlantic States than do the Lake Scugog 
data; 19 of the 30 recoveries came from the coastal states from New 
York to Maryland. There are 2 records from South Carolina but none 
from North Carolina, Virginia, or Long Island. Recoveries have been 
taken also in Ohio (3), Michigan (1), and Missouri (1). 
New York 
During the past 25 to 30 years at least six major banding 
stations have been in operation at various times in New York State, 
exclusive of Long Island. These have been fairly well dispersed from 
east to west across the state. Resulting data (2,121 recoveries) give 
excellent patterns of distribution showing the relation of the New York 
State black ducks to both the Atlantic and Mississippi Flyways. 
The Lake Alice and Tomhannock Reservoir stations have already 
been discussed. Other stations are the Oak Orchard Game Management Area, 
Rochester, Cayuga Lake, Montezuma Refuge, Oneida Lake, and Perch Lake. 
With the recoveries for each of these stations mapped, variations in 
the distribution patterns between stations 50 to 100 miles apart are 
apparent. In general, the farther west in New York, the more influence 
there is from the Mississippi Flyway and the interior of the Atlantic 
States. For practical management purposes, it would appear that most 
of the records, direct and indirect, from Perch Lake, Montezuma, Oneida 
Lake, and Cayuga Lake agree so closely that these stations could be 
considered as a unit. 
Principal differences in the migration pattern seem to be 
(1) that in the Chesapeake region, the Perch Lake records are relatively 
more predominant on the Eastern Shore, and (2) that there is a wider 
spread of recoveries into central New England to the east and the Miss- 
issippi River area to the west from the Perch Lake station than from 
the other three. 
Greatest difference between stations seems to be in the 
numer of recoveries within a 50-mile radius of the banding station. 
In the Montezuma region, this reaches 45 percert for direct recoveries 
and 32 percent for the indirect. Perch Lake recoveries amount to 24 
percent for directs and 12 percent for indirects. 
From the 296 mapped direct recoveries there is no indication 
of any particular route of travel across New York State. The birds 
probably leave upper New York by diverse routes, some eventually coming 
in on the lower Hudson River. Others apparently fly the Susquehanna 
and Delaware River systems in Pennsylvania, as evidenced by scattered 
recoveries (fig. 13). 
South of Pennsylvania the birds diffuse over much of the 
Middle and South Atlantic Coastal States. Recoveries are most numerous 
in tidewater areas, though there are some inland records, particularly
