Two hundred rabbit traps were constructed by project personnel during the 
^ month. These will be used to inventory cottontail populations and collect experi¬ 
mental animals on the various studies and management evaluations which comprise 
objectives of the rabbit project. 
Detailed planning was continued on the study to evaluate supplementary feed¬ 
ing to reduce rabbit damage to the home landscape, gardens, nursery, and forest 
plantings. Planning was initiated on the study of rabbit population dynamics in 
response to hunting. Planning was also initiated on the evaluation of effects of 
habitat manipulation on cottontail abundance.

Experience gained while night-1ighting pheasants suggests that bobwhites can 
be successfully captured by night-1ighting during the late summer and early fall. 
Consequently, a vehicle was outfitted for capturing quail and prairie chickens by 
night-1ighting. Plans were formulated for censusing prairie chickens in the east- 
southeast region of the state.

Pheasant brood counts were conducted on the Donovan, Beaverville, and Iroquois 
areas during July and August. The Donovan and Iroquois areas were treated with 2 
pounds per acre of aldrin during the spring of I960 and 1961, respectively. The 
Beaverville area was not treated in I960, 1961, or 1962. 
The number of pheasant broods observed per mile on the Donovan area in 1 962 
(0.111) was 56.3 per cent greater than in 1 96 1 (0.071) and 217*1 per cent greater 
than in I960 (0.035)* A total of 16.8 per cent of the hens observed on the Donovan 
area in 1 962 were broodless compared to 18.7 per cent in 1 96 1 and 43*4 per cent in 
I960, the year of treatment. 
The number of pheasant broods observed per mile on the Beaverville area in 
1962 (0.110) was 11.1 per cent greater than in 1 96 1 ( 0 . 099 ) and 139*1 per cent 
greater than in i 960 (0.046). A total of 19*0 per cent of the hens observed on the 
Beaverville area in 1 962 were broodless compared to 16.8 per cent in 1 96 1 and 34.6 
per cent in i 960 . 
The number of pheasant broods observed per mile on the Iroquois area in 1 962 
(0.118) was 372 per cent greater than in 1 96 1 (0.025). A total of 18.1 per cent of 
the hens observed on the Iroquois area in 1962 were broodless compared with 45*5 par 
cent in l$6l, the year of treatment. 
In 1962, the average brood size for all ages, for those broods for which com¬ 
plete counts were possible, on the Donovan, Iroquois, and Beaverville areas was 
7.6, 8.5> and 7*6 chicks, respectively.
