Weather and Water Conditions 
In 1959, with the exception of northwestern Iowa, this 
State had recovered from temporary drought. Heavy rains during 
May throughout the entire State improved and created much addi- 
tional nesting habitat. Unoccupied dry areas in northwest Iowa, 
which were filled or partially filled by heavy rains in May were 
immediately occupied by nesting ducks, especially blue-winged 
teal. Habitat conditions remain excellent throughout most of 
Iowa indicating better than average production and survival of 
young waterfowl. 
Breeding Population and Production Data 
Unusually large numbers of nesting blue-winged teal and 
mallard have been reported in Iowa in 1959. Habitat which has 
been sparsely occupied by nesting ducks during the last decade in 
southwestern, southcentral, and in east and northcentral Iowa is 
much more productive this year. Many brands have already been 
reported from these areas. 
Limited information from stream surveys indicate the 
wood duck population trend in Iowa is slightly upward. Habitat 
conditions and broods reported to date suggest better than 
average production and survival of this species. 
Conclusions 
Tt is anticipated that the fall flight of ducks from 
Towa this year will be somewhat larger than in 1958.
