Pacific Flyway 
Lower Klamath, California The late nesting season caused a reduction of 
68 percent in Canada goose production in the number reported in 1949 with a decrease 
in broods from 45 in 1949 to 23 this season. Late nesting successes, however, increased 
duck production 27 percent over the numbers reported in 1949, Coot aruwufetior also 
improved 23 percent over the 1949 number. 
Sacramento, Colusa, and Sutter, California Of several hundred mallards 
present during the season, only 6 nests and 10 broods were found. The total duck pro- 
duction was estimated to have declined 10 percent from last year at the Sacramento | 
Refuge. One abandoned goose nest with 2 eggs was found. At Sutter Refuge 130 mallards 
and 20 cinnamon teal were produced. Only 30 mallards were produced on the Colusa 
Refuge. This represented 8 broods. 
Tule Lake, California The late nesting season caused a 77 percent reduction of 
Canada geese production from the 1949 estimate, there being a decrease in goose broods 
from 103 in 1949 to 31 this season. On the other hand late nesting success caused an 
increase of over 51 percent in duck production over 1949 numbers and a 9 percent increase 
in coots. 
Camas, Idaho Nesting did not begin until the middle of June. The broods appeared 
late but hatch and survival were good. One hundred seventy-nine broods with 899 young 
were observed. The high vegetation made observations difficult, but it is estimated 25 
percent of the broods were seen. A 25 percent decline in total goose production occurred 
but an increase from 13 to 39 brood numbers was recorded. Production of ducks increased 
only slightly, 2,962 in 1950 as compared with 2,500 for 1949. 
Deer Flat, Snake River, Idaho The resident population of geese was estimated at 
35, most of which were non-breeders or breeders whose nests were destroyed by flooding. 
Only 2 successful nesting pairs were observed and these produced 4 goslings. This is not 
a suitable waterfowl nesting refuge because of extreme water level fluctuation with a: 
maximum level in April, dropping in May to build up in june, and then dropping rapidly 
until fall, Nests are thus destroyed by flooding. Nevertheless, thirty-six broods, twenty- 
four of which were mallards, were observed with 750 young. Also nine broods of coot 
with 50 young were noted. This compares favorably with the 1949 breeding records when
