CENTRAL FLYWAY 
WYOMING 
are 
Weather and Water Conditions - Weather in Wyoming was character- 
ized this year by a warm spell early in the spring followed by cold, moist | 
weather throughout much of April and May, Water conditions during the early 
spring were slightly below average and drought conditions prevailed in some 
sections of the State by early summer. By July, a critical shortage of surface 
water existed throughout the northwest and central portions of the State. 
Breeding Population Indices - Aerial surveys during May resulted in an 
gatimate of 13,725 breeding pairs in the State plus 16,789 birds which were 
classéd as migratory. This was about the same.number as were present 
during 1952, Mallards represented 62 percent of the breeding pairs with — 
gadwall,: green-winged teal and merganser comprising the remainder. 
' The aerial surveys also resulted in.an estimate of 1, 900 Canada geese, 
of which 670 represented the nesting population, This represented a 15 percent 
increase ower 1952, 
Production Index - No estimate on total duck production was obtained although 
gomparisons between 1952 and 1953 indicate that production decreased 
| gonsiderably this year. ne 
Goose production studies indicated that the average brood size was 
4dentical with last year, although there was a 25 percent decrease in birds 
; produced in all areas as compared to 1952. | 
Conclusions - The fall flight of ducks from Wyoming this year will be 
Peewee . 
gonsiderably below last year and the flight of geese will be about 25 percent 
jless,.

loth er 
-Weather and Water Conditions ~ Mild open winter, Spring and Summer 
‘10 days to 2 weeks; water about the same as in 1952, 

torms delayed breeding 
prceeing Population Indices - New transects are being established, Comparison 
old ones show 19.01 pairs per square mile in 1952 and 13,17 in 1953, a 
31 percent decrease, 
, Tatoos ~ Brood counts covered 37.8 square miles in the Sandhills region 
nd as compared to last year there was a reduction of 59 percent in the number 
of broods, Further, the average brood size decreased to 6,2 from a 5-year 
average of 7.0. 
* Conclusions - Nebraska will contribute considerably fewer birds to the fall
