Success of the Season 
Evidence of some nest destruction in the early nesting mallards and pintails 
has been apparent in the sandhills. Newly hatched broods of these species observed. 
rather late in the season would seem to indicate that at least some of this loss was 
made up by re-nesting. The uniform age of the broods observed on the mid-July 
brood counts indicated a somewhat late hatch with a high peak for all species. Poss- 
ibly the May storm caused this general delay.
