GEESE 
In contrast to the status of ducks, both 
the Canada goose and brant populations 
during the 1961 winter survey reached the 
peak levels recorded in at least the past 
decade. Since production data are lacking, 
average) production is assumed. Therefore, 
for Canada geese and brant it is estimated 
that the fall flight will be about the same 
as last year but moderately larger than 
the flight in 1959. 
cOOT 
The production of coot in all important 
breeding areas is expected to be markedly 
reduced by drought conditions. Therefore, 
a major reduction in the fall flight of 
this species is expected.
