Effects Of Competition And Predation On Prothonotary Warblers And House Wrens Nesting In Eastern Iowa, Timothy Brush Mar 1994

Effects Of Competition And Predation On Prothonotary Warblers And House Wrens Nesting In Eastern Iowa, Timothy Brush

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

In a fragmented midwestern floodplain forest, a small Prothonotary Warbler (Protonotaria citrea) population experienced high competition with House Wrens (Troglodytes aedon) and mammalian nest predation in 1988-89. Despite the provision of 3 types of nest boxes and higher water levels, Prothonotary Warblers did not nest successfully and decreased in the fragmented forest in 1990-91. House Wrens used >90% of the nest boxes in both years. Wren territories doubled within the nestbox area, while remaining constant on an unmanipulated area. In contrast, a larger warbler population had high nesting success during 1990-91 in a relatively unfragmented, wetter forest tract. Such forests, …

Artificial Cavity Box Use By Eastern Screech Owl, Otus Asio, Lori A. Davis Jan 1994

Artificial Cavity Box Use By Eastern Screech Owl, Otus Asio, Lori A. Davis

Masters Theses

Screech owl use of 29 artificial cavity boxes placed in wooded habitat on a 14.6 hectare study area in east central Illinois was monitored from 1975 through 1993. A total of 28 screech owls were captured a total of 155 times. Two to 4 adults were usually present and 3 broods were reared in the boxes. The time between first and last capture of birds taken 4 or more times ranged from 270 to 2589 days (average 1740 days). Home range of 5 owls captured 8 to 17 times ranged from 0.45 to 6.0 ha. Cavity boxes were used more …

Modelling Avian Distributions Of The Navarrese Region In Northern Spain With A Geographic Information System, Samuel Soret-Garcia Jun 1993

Modelling Avian Distributions Of The Navarrese Region In Northern Spain With A Geographic Information System, Samuel Soret-Garcia

Loma Linda University Electronic Theses, Dissertations & Projects

GIS (Geographic information Systems) technology was used for identifying relations between environmental characteristics and the breeding distributions of nine avian species of the Navarrese region in northern Spain. Data overlays of multiple GIS layers derived the explanatory variables for modelling the breeding distributions from logistic regressions. A spatial autocorrelation analysis was conducted to characterize the distribution patterns and to incorporate spatial factors (neighborhood effects) into their analysis.

All nine patterns analyzed exhibited a high level of spatial autocorrelation. Accordingly, the basic hypothesis of spatial randomness was rejected in favor of spatial clustering for the sample data. The breeding distributions strongly …

Samuel Aughey’S List Of Nebraska Birds (1878): A Critical Evaluation, Roger S. Sharpe

Nebraska Bird Review

The University of Nebraska was founded in Lincoln in 1869, but finances did not allow the addition of a scientist until 1875, when Samuel Aughey was added to the staff to fill the first chair of natural history (Pound and Clements 1900). Although a theologian by training, Aughey wrote prolifically on a number of natural history subjects pertaining to Nebraska, including its flora, fauna, and geology. A summary of his impressions of the natural history of the state, including its biota, was published in a book, "Sketches of the Physical Geography and Geology of Nebraska" (Aughey 1880), which was printed …

An Investigation Of The Host Specificity Of The Brown-Headed Cowbird, Brian D. Peer Jan 1993

An Investigation Of The Host Specificity Of The Brown-Headed Cowbird, Brian D. Peer

Masters Theses

We attempted to determine the factors associated with the lack of parasitism of the Common Grackle (Quiscalus quiscula) by the Brown-headed Cowbird (Molothrus ater). We investigated the breeding phenology of the two species, the responses of colonial- and noncolonial-nesting grackles to female cowbird models, the frequency of artificial egg rejection by grackles, incubation success of cowbird eggs transferred into grackle nests, and the survival rates of cowbirds cross-fostered into grackle nests.

By the time cowbirds began egg-laying at our study sites, 88.5 % of all grackle nests were beyond the point of successful parasitism. Grackles responded …

Should We Export Our Native Birds?, Ross Kingwell Jan 1993

Should We Export Our Native Birds?, Ross Kingwell

Journal of the Department of Agriculture, Western Australia, Series 4

The export of Australia's native birds is prohibited by the Wildlife Protection (Regulation of Exports and Imports) Act 1982. A review of the Act in 1991 has not led to any relaxation of the export ban.

However, the review recommended that government examine "the practical aspects of establishing a fully funded administrative control mechanism to allow strictly regulated commercial exports of a limited number of species of captivebred native birds which are not endangered or threatened". In making this recommendation, the report acknowledged there may be a case for highly regulated export of some native bird species.

This article explores …


Enteric Coccidia (Apicomplexa) In The Small Intestine Of The Northern Spotted Owl (Strix Occidentalis Caurina), Eric P. Hoberg, R. J. Cawthorn, O. R. Hedstrom Jan 1993

Enteric Coccidia (Apicomplexa) In The Small Intestine Of The Northern Spotted Owl (Strix Occidentalis Caurina), Eric P. Hoberg, R. J. Cawthorn, O. R. Hedstrom

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Sporulated oocysts (mean dimensions = 13.0 x 10.8 μm) and sporocysts (11.3 x 5.5 μm) of a coccidian resembling Frenkelia sp. or Sarcocystis sp. were present in the lamina propria of the small intestine of a naturally-infected northern spotted owl (Strix occidentalis caurina) collected near Medford, Oregon, USA. Dimensions of these oocysts and sporocysts appear to be considerably smaller than those from other sarcocystid species with avian definitive hosts. Additionally, numerous developmental stages and unsporulated oocysts (mean dimensions 22.8 x 17.8 μm) of a possible species of Isospora also were observed in the intestinal epithelium. This constitutes the …


The Effects Of Nest-Box Visibility And Proximity On The Frequency Of Brood Parasitism In Wood Ducks, Roger W. Jansen Jan 1993

The Effects Of Nest-Box Visibility And Proximity On The Frequency Of Brood Parasitism In Wood Ducks, Roger W. Jansen

Masters Theses

I studied the effects of nest box visibility and clustering on the rate of intraspecific brood parasitism (IBP) in Wood Ducks (Aix sponsa) at Lake Shelbyville Fish and Wildlife Area in Moultrie County, IL from 2 March 1992 to 22 June 1992. Sixty-eight percent of the nest boxes sampled were used and 33% of the nests were destroyed by predators. Mean clutch sizes of unparasitized (x = 9.2) and parasitized (x = 15.2) nests were significantly different. The parasitism rate in Wood Duck nests was 54%. More visible boxes had a tendency to be parasitized at a higher rate than …

Larids, Scolopacids, And Passerines Exploiting Ephemeral Prey At Talan Island, Russia, Eric P. Hoberg, Alexander I. Kondratiev, Alexander S. Kitaysky Oct 1992

Larids, Scolopacids, And Passerines Exploiting Ephemeral Prey At Talan Island, Russia, Eric P. Hoberg, Alexander I. Kondratiev, Alexander S. Kitaysky

Harold W. Manter Laboratory of Parasitology: Faculty Publications

We report an unusual multispecies foraging assemblage that included larids, shorebirds and passerines which exploited a highly concentrated and ephemeral prey source over a period of three days in July and August 1988. During studies of breeding biology, food-habits and host-parasite ecology among a diverse colonial avifauna at Talan Island in the northern Sea of Okhotsk (59°18'N; 149°02'E) we observed the formation of mixed-species flocks during extreme high tides of July 31, August 1, and August 13, 1988.
