la comparison with, some of the other species of ducks the mssaber 
of mllards handled was comparatively small, as only 72 war© handed and 
released during the three seasons in which this work was carried on. Of 
these, 22 - a little more than 30 per cent • were hilled and reported 
subsequently (see Table 1)* Seven were secured near the mouth of Bear 
River within a few miles of their place of release, 6 of them, and 
possibly 7, during the fell in which they had been mrked. The other 15 
individuals divide into two main groups, one in which the birds remained 
until late fell or winter in the same general region as the mouth of Bear 
River, and the other in which they made extended migrations to other regions.

Bear River near Tremonton not far in an air line from the mouth of the streaty.
