made up 4.7 per cent of the kill in Louisiana, 8.0 per cent in 
Mississippi, and 30.8 per cent in Alabama. The sample from Louisiana 
was poorly distributed and probably did not properly sample the 
greater part of the ringneck kill in Bhe State (Smith, letter of 
Oct. 7, 1960). Samples from Mississippi and Alabama were small. 
Greater scaup were taken in smal¥ numbers throughout the 
Flyway, but they made up a significant portion of the bag (7.0 per 
cent) Only in Michigan. 
Buffleheads were most common in the northern tier of States 
and Ohio, where their proportion in the kill increased from west 
to east. They were most abundant in Miepaeats where they made up 
5-3 per cent of the kill. 
Black x mallard hybrids were scarce in the kill of all States, 
although some may not have been recognized. They were most numerous 
in the kills from Wisconsin and Indiana, and virtually absent in the 
kills from the southern half of the Flyway. It is possible that the 
one hybrid listed for Louisiana was a mottled duck. 
The extent to which species composition, as determined from 
the wing collection, varies among different areas within the same 
State was examined in the data from Minnesota. Wing samples from 
Minnesota were divided into four groups that came from zones that 
conformed roughly to the known distribution patterns of species 
abundance (Figure 4). The number of wings from mallards, green- 
winged teal, blue-winged teal, lesser scaup, and ring-necked ducks 
was determined for each of these areas and the species composition 
calculated. The species considered were the five most common species 
in the Minnesota kill, and collectively they made up 77.3 per cent 
of the State total. The proportions of these five species in the 
kill in each of the four regions are shown in Table 17 and Figure 4. 
The table also shows the relative proportions of the kill of all 
species for each regione 
Mallards made up 31.3 per cent of the State kill. Their 
proportions were approximately equal in the northwestern, north- 
central and southern parts of the State. In the northeastem area, 
however, mallards made up only 19 per cent of the total kill. 
Green-winged teal made up a sizeable portion (18.4 per cent) 
of the kill in the southern zonee They were proportionally less 
numerous in the northern areas: they made up about 7 per cent of 
the kill in the northwestern and only about 2 per cent of the kill 
in the northcentral and northeastern areas.
