: 
In considering the information available, the 1950 breeding season appears to 
be slightly better than last year, due to better water conditions across the northern and 
western parts of the State. 
J .Thirteen species of ducks were. recorded as nesting in Nevada. Species in order 
of production according to number of broods and young seen for the river and reservoir 
survey here: Mallard, gadwall, pintail, green-winged teal, cinnamon teal, redhead, 
lesser scaup, baldpate, shoveler, ruddy duck, and blue-winged teal. 
For the marsh survey the order by species is redhead, cinnamon teal, canvas- 
back, gadwall, mallard, shoveler, ring-necked duck, ruddy duck, lesser scaup, bald- 
pate, and pintail. . 
The peak. in numbers of broods seen occurred during the latter part of July on 
the river and reservoir survey. 
The first year's survey indicates 10. 4 ducks per square mile for river transects: 
53.6 pairs per square mile of reservoir habitat sampled, and 64.5 pairs per square mile 
of marsh habitat. (Stillwater Wildlife Management Area.) 
Broods per square mile were found to be 5.26 for the river iHinmects, 63.5 for 
reservoir habitat and 68.2 for Ruby Marshes with 11.7 for Stillwater Marshes.
