Female No. 44 was live trapped three times in 1957, once in 1958, twice in 1959, 
and was live-trapped and removed from the area on September 9, I960. Female No. 
76 was first trapped on August 2, 1957, and was retrapped on June 8, 1958. It was 
not trapped in 1959 but was killed by a hunter on November 5, 1960. Of 146 rac¬ 
coons first marked in 1957 and 1958, 30 per cent have either been killed or were 
known to be alive in I960.

Final analysis of hunting data revealed that a minimum of 111 cocks were 
bagged on the Neoga area during the 1960 season. Two hundred and sixty-one hunters 
in 105 parties expended 571 gun-hours to bag 93 of the cocks, representing an 
effort of 6.14 gun-hours to bag 1 cock. In addition, 21 cocks were crippled and 
not recovered. The location of kill of 103 of the bagged cocks was determined, 
and 87 (84.5 per cent) of these cocks were bagged within an area of 8 sections. 
The age ratio for 89 of the bagged cocks was 10.1 juveniles per adult. An estimate 
of the number of young produced per adult hen is computable from the age ratio of 
bagged cocks and the preseason sex ratio by using the formulas below. In these 
formulas, the sex ratio among juvenile pheasants is assumed to be equal. 
1 adult cock + 10.1 juvenile cocks per adult cock 
x adult hens + 10,1 juvenile hens per adult cock 
then 
x = 4.7 adult hens per adult cock 
10.1 juvenile cocks + 10.1 juvenile hens =

Therefore, 4.30 young of both sexes were produced per adult hen. During July and 
August, 53 per cent of the hens observed were accompanied by broods. If we assume 
that 53 per cent of the hen population were productive, then 8,11 young were pro¬ 
duced per productive hen. The observed average brood size during the breed ing 
season was 8.52 young. 
Calculations made from changes in the pre- and post-season sex ratios and 
the per cent of pre-season marked cocks that were bagged produced estimates of 
the pre-season population of 626 (269 cocks and 357 hens) and 777 pheasants (333 
cocks and 444 hens), respectively. These estimates indicate that 39.6 to 49.1 
per cent of the cocks were bagged or crippled by hunters.
