An attempt has been made to set up brood trend routes in some of 
the important duck producing areas of the State. These routes are runina 
standardized manner in that during the first count all broods are recorded and 
on the second count only Class I broods are counted. The total broods seen are 
compared on a trend basis. 
Only the results from southeastern Idaho are available at this 
time. These are givenin Table 2. It is believed that the results obtained in 
this area this year are quite misleading. The duck hatch is definitely late and 
on the second count, 82 percent of all broods encountered were Class I. Itis 
apparent that this count was made while the main hatching period was still in 
progress. So, although the total number of broods seen was down, it is believed 
the areas will produce quite a few more birds than is indicated.

Conclusions - 
It is estimated that the goose flight from Idaho this year will be 
less than in 1954, while the duck flight will be about the same.
