The decrease in the number of ducks counted in Box Elder, 
Weber, Davis and Salt Lake counties is the result of the drought con- 
ditions that existed in those areas this year. A large portion of the 
marshy areas in those counties that are normally wet were quite dry 
when the census was taken. This has caused the birds to concentrate 
around availeble water areas, which may not be in a flight transect, 
thereby causing a decrease in the number of birds observed on those 
flight lines.
