MARI LA VALISINERIA. 
Canvas-backs are extremely rare ducks at Wenham, but 
not so rare as Gadwall, Shoveler, or Ring-necked Scaup. 
Thirteen have been taken or about four-tenths of one per 
cent. These ducks were taken in six of the twenty seasons, 
the dates being as follows: November 13th, 1902, November 
4th, 1905, November 3rd, 1909, November 1st, 1914 and 
November 14th, 1916.

The Greater Scaup is not a common species on Wenham 
Lake. During the nine years when this and the Lesser 
Scaup were recorded separately, only thirty-three were 
taken, as against two hundred and thirty-two of the Lesser. 
Thus the big Scaup probably occurs in the proportion of 
about fourteen per cent to the Lesser Scaup. As the total 
number of Scaup of both species taken is five hundred 
and ten, the probable number of Greater is about seventy- 
one. This represents a status of two and four-tenths per 
cent. Of course the Greater Scaup as we see him here is 
largely a coastal bird, and a late migrant. This figure 
would have to be greatly increased to represent actual 
numbers in the County, but it is probably very nearly right 
for the species in fresh water, near the coast. 
MARILA AFFINIS . 
The Lesser Scaup is the second most abundant duck. 
Out of the total number of five hundred and ten of both 
species, it is probable that at least four hundred and thirty- 
nine were of this species, as explained under the last 
species. Thus the small Scaup is about eighty-six per 
cent of all Scaups, and fifteen per cent of the total ducks 
shot. As they come very easily to decoys, and often in 
compact flocks, it may be that fifteen per cent is really too 
large to represent the actual status. Probably ten to 
twelve per cent would be more nearly correct. The appear¬ 
ance of this duck is very regular and varies scarcely more
