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.
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 …

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
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
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 …

The purpose of this paper is twofold: first, to evaluate the usefulness of various karyotypic procedures using domesticated and passerine birds and second, to comment on the validity of the application of karyotypic data to taxonomy.
The Social Organization Of Wild Turkeys On The Welder Wildlife Refuge, Texas, Charles Robert Watts
The Social Organization Of Wild Turkeys On The Welder Wildlife Refuge, Texas, Charles Robert Watts
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study is of the social organization of the wild turkey (Meleagris gallopavo intermedia Sennett) on the Welder Wildlife Refuge in southern Texas.
The earliest turkey nests hatched in April, with the peak of hatching a month or more later. These poults may remain with their mother until winter. This brood flock, however, often combined with other brood flocks to form composite brood flocks when the poults were a few weeks old. Hens not successful in rearing young combined into broodless flocks.
The juvenile males left the brood flocks in late fall or winter. They remained a distinct unit, …

Behavior Of The Red-Footed Booby (Sulasula) In British Honduras, Jared Verner
Behavior Of The Red-Footed Booby (Sulasula) In British Honduras, Jared Verner
LSU Historical Dissertations and Theses
During three months of the breeding season in a colony of 3500 Red-footed Boobies (Sula sula) on 45½-acre Half Moon Caye, fifty miles east of Belize, British Honduras, that species’ little-known breeding activities were investigated. Feeding flights of boobies began leaving the caye before daylight and returned in the evening until after dark. Wind direction and velocity notably affected the mode of the birds’ departure but little affected their direction. Average flight-unit size was 2.41 birds. Contrary to published accounts, the boobies were able to take flight from the ground.

Life Histories Of North American Nuthatches, Wrens, Thrashers And Their Allies: Order Passeriformes, Arthur Cleveland Bent
Papers in Ornithology
An attempt has been made to give as full a life history as possible of the best-known subspecies of each species and to avoid duplication by writing briefly of the others and giving only the characters of the subspecies, its range, and any -habits peculiar to it. In many cases certain habits, probably common to the species as a whole, have been recorded for only one subspecies. Such habits are mentioned under the subspecies on which the observations were made. The distribution gives the range of the species as a whole, with only rough outlines of the ranges of the …
