MISSISSIPPI FLYWAY 
Up to the present time, 60 wood type and 24 metal type 
nesting boxes have been inspected for evidence of successful clutches. 
This year, six successful clutches were found, compared to eight in 
the same 84 boxes in 1956, Percent usage in 1957 is 7.1 percent, 
compared to 9.5 percent in 1956. 
A limited aerial brood survey of approximately 50 square 
“miles of pothole and river marsh habitat was conducted again, this 
year on June 27. Six broods were observed--three mallard, one black 
duck, and two blue-winged teal, compared to nine in 1956, five in 1955, 
and 28 in 1953. 
Conclusions 
It is estimated that the production of wood duck in Indiana 
will be somewhat greater than it was in 1956, although it will still be 
below the average of the past five years,
