Nesting Dynamics Of The Eastern Bluebird (Sialia Sialis) In Southeastern Illinois, Susan E. Nelle
Nesting Dynamics Of The Eastern Bluebird (Sialia Sialis) In Southeastern Illinois, Susan E. Nelle
Masters Theses
Data collected from 1981 through 1988 from an Eastern Bluebird (Sialia sialis) nesting box trail, involving 512 nests and 2176 eggs, in Crawford County, Illinois, were analyzed and compared to similar published works. The average nesting season lasted 167.4 days, ran from 17 March through 31 August, and was divided into three breeding peaks (or phases). Most breeding pairs were observed with either one or two clutches per season; however, triple-brooded pairs were also present, the clutches of which coincided well with the three peaks. Most data showed a decrease as the season progressed. For example, mean clutch …
Operant Conditioning In The Psittacine, Amazona Amazonica, Gloria J. Nadolski
Operant Conditioning In The Psittacine, Amazona Amazonica, Gloria J. Nadolski
Masters Theses
Two Orange-winged Amazon Parrots, (Amazona amazonica) were subjected to operant conditioning involving three tests: two-choice spatial discrimination and reversal, three-choice color discrimination and reversal, and the oddity principle. Results of the habit reversal tests were compared to those of Gossett (1968) to determine the phylogenetic ranking of the learning capabilities of psittacines. In the first two habit reversal tests, the subjects completed twenty reversals using sunflower seeds as positive reinforcements. In the oddity principle test, the parrots completed the equivalent of 20 reversals, again using sunflower seeds. Criterion was met when they completed 8 consecutive correct choices with …
Seasonal Lekking Behavior Of The Greater Prairie-Chicken In Illinois, Scott A. Simpson
Seasonal Lekking Behavior Of The Greater Prairie-Chicken In Illinois, Scott A. Simpson
Masters Theses
Spring behavior of prairie-chickens (Tympanuchus cupido) has been studied extensively, however there is little information on fall-winter lekking activity. Greater prairie-chickens were observed weekly on a lek from 25 September 1982 to 23 June 1983 during morning and evening hours in Jasper County, Illinois. The peak number of prairie-chicken males on the lek occurred in February although hen attendance did not occur until 10 March 1983. All spring lekking activities were higher compared to that of the fall-winter period. Fall-winter lek activity was aggression which centered on probably brief, less intense male aggression which probably establishes or maintains …
Evaluation Of Potential Wild Turkey Habitat In Eastern Illinois, Cara B. Daugherty
Evaluation Of Potential Wild Turkey Habitat In Eastern Illinois, Cara B. Daugherty
Masters Theses
Reestablishment of the wild turkey has been successful in the southern part of Illinois where large established tracts of woodland occur. However, turkeys are capable of surviving in areas with less forest cover, if food, nesting materials and protection are available. This project evaluated the potential turkey habitat of a 14-county area of eastern Illinois along the drainage of the Wabash River. Six potential release sites were selected and the habitat evaluated. In these areas, oak (Quercus spp.) and hickory (Carya spp.) were the dominant tree species. Disturbance from human populations was determined in each of …
Coccidian Parasites Of Wild Turkeys, Meleagris Gallopavo Silvestris, In Illinois, D. Michael Watkins
Coccidian Parasites Of Wild Turkeys, Meleagris Gallopavo Silvestris, In Illinois, D. Michael Watkins
Masters Theses
Fecal samples from 124 wild turkeys (Meleagris gallopavo silvestris), collected in three southern Illinois counties, were examined for coccidia. Three and two tenths percent (4) of the birds sampled were infected with Eimeria of apparently four different species. These species were tentatively designated as: E. meleagridis, E. adendeides, E. meleagrimitis and E. subrotunda.
Production And Utilization Of Sunflower Food Plots At Shelbyville Wildlife Management Area, Illinois, Duane T. Dust
Production And Utilization Of Sunflower Food Plots At Shelbyville Wildlife Management Area, Illinois, Duane T. Dust
Masters Theses
Three sunflower (Helianthus annuus) fields from 3.2 ha to 1.0 ha in size, planted on the Shelbyville Wildlife Management Area, Illinois were analyzed for seed production and utilization by birds. Seed in heads and on the ground were sampled and species and numbers of birds in the fields were censused at two week intervals from September, 1976 to February, 1977. Decline in seed availability was most rapid in the smallest field and least rapid in the largest field. Fields and portions of fields adjacent to wooded cover were also utilized more rapidly. American goldfinch (Spinus tristis) …
Blood Parasites Of Illinois Wild Turkeys, Ulrike G. Guenthner
Blood Parasites Of Illinois Wild Turkeys, Ulrike G. Guenthner
Masters Theses
Blood smears, from 152 wild turkeys (Meleagris gallopavo silvestris) killed during hunting seasons in southern Illinois, were examined for blood parasites. Haemoproteus meleagridis infected 34% of the 83 adult and 19% of the 69 immature turkeys. Of the infected birds, 54% had one or two infected cells per 5000 erythrocytes and 78% had one to five. Infection rates were significantly higher in counties along the Mississippi River than in Pope County, located about 40 miles east of the river. Other parasites specifically searched for but not found were Leucocytozoon, Plasmodium, Trypanosoma and microfilaria.

Homing Studies Of Bank Swallows In Eastern Illinois, Jennifer Eileen Hagerstrom
Homing Studies Of Bank Swallows In Eastern Illinois, Jennifer Eileen Hagerstrom
Masters Theses
A series of homing experiments using 39 color-marked Bank Swallows (Riparia riparia) were carried out in eastern Illinois during the summer of 1975. The swallow colony was located four km east-northeast of Charleston, Illinois at the Charleston Stone Quarry. Eight release sites were located in the four compass directions from the home colony at distances of 14.4 to 32.3 km away.
The colony was approached before dawn and swallows were captured using tube traps. Birds were color-marked, banded, and taken in individual bags to the release site by automobile. Cloud cover, wind velocity, wind direction, and orientation behavior …
Pesticide Residues In The Illinois Wild Turkey, John M. Bridges
Pesticide Residues In The Illinois Wild Turkey, John M. Bridges
Masters Theses
Adipose tissue from 55 turkeys, killed during the 1974 hunting season in southern Illinois, was grouped by age and location of the birds, and the pesticide concentrations in them were determined by gas/liquid chromatography. Twelve different pesticides were identified in the samples with only four, total DDT, heptachlor epoxide, toxaphene, and linuron, being present in all samples. Concentrations ranged from 0.02 ppm to 0.88 ppm.

Status Of The Wild Turkey In Southwestern Illinois In 1970, Robert Merle Cottingham
Masters Theses
Wild-trapped turkey were first released in southwestern Illinois in 1959. This, and subsequent releases have established a huntable population of wild turkey in the area. Until 1970, no evaluation of the status of the bird had been made. This study was conducted in June, July, August and September, 1970, to determine the distribution, productivity and relative abundance of the wild turkey in Alexander, Jackson, Union and Williamson Counties and to make recommendations for future management of the population. Information was supplied by rural mail carriers, Illinois Department of Conservation and U. S. Forest Service personnel and local residents together with …

Helminth Parasites Of Illinois Wild Turkeys, James W. Jackson
Masters Theses
Viscera from 69 wild turkeys (Meleagris gallopavo silvestris) collected from Jackson, Union and Alexander counties, Illinois, were examined for helminth and coccidian parasites. A total of eight species of parasites was found, all in the alimentary tract. The coccidian parasite Eimeria sp. was found in 9.6% of birds examined. The nematodes Heterakis gallinarum, Ascaridia galli and Ascaridia dissimilis were found in 13.2%, 27.9% and 48.5% respectively of all birds examined. Three species of cestodes, Raillietina williamsi, Metroliasthes lucida and Hymenolepis sp., were recovered from 41.1%, 27.9% and 1.4% respectively of birds examined. One species of trematode, …

Gastro-Intestinal Helminths Of Illinois Bobwhites, Michael Eugene Gordon
Masters Theses
The viscera of 103 bobwhite quail (Colinus virginianus), from east central Illinois counties, were collected during November and December of 1971 and examined for helminth parasites. Two nematodes were identified: Dispharynx nasuta (9.7%) and Ascaridia sp. (7.8%). The rate of infection varied significantly between counties but there was no difference in parasitism of males and females.
A Comparison Of Nocturnal Restlessness Of Caged Thrushes And Migration Of Free Thrushes, Charles Goodwin Kjos
A Comparison Of Nocturnal Restlessness Of Caged Thrushes And Migration Of Free Thrushes, Charles Goodwin Kjos
Masters Theses
Nocturnal activity (Zugunruhe) of eight caged, radio-tagged thrushes (Hylocichla spp.) was compared by signal analysis with the occurrence of migration in 16 free, radio-tagged thrushes over a 37-night period during the autumn of 1970 in central Illinois. The study was conducted to determine the extent of synchrony of Zugunruhe and migration in these nocturnal migrants in fall. Zugunruhe frequently occurred on nights when there was no migration, but migration occurred only on nights when at least 50 per cent of the caged birds were active. Except for one departure which was atypical in several respects, migration occurred …
