Nest Predators And Breeding Birds: Do Initial Vocalizations Correlate With Predator Type And Future Defense Strategy?, Bradley M. Gottfried, Michaela Haug, Kathryn Andrews Jan 1984

Nest Predators And Breeding Birds: Do Initial Vocalizations Correlate With Predator Type And Future Defense Strategy?, Bradley M. Gottfried, Michaela Haug, Kathryn Andrews

Journal of the Minnesota Academy of Science

The initial vocalizations of breeding catbirds in response to predator models positioned at their nests were analyzed to determine if they were correlated with the type of later defense employed (attack model vs. no attack), intensity of defense, and type of predator model (snake vs. blue jay). Statistical differences were found in the types and numbers of vocalizations used in relation to type of nest predator and form of future defense. The data suggest that the initial catbird vocalizations may indeed encode a variety of information.


Recoveries Of Great Horned Owls Banded In Central Minnesota, Robert T. Bohm Jan 1984

Recoveries Of Great Horned Owls Banded In Central Minnesota, Robert T. Bohm

Journal of the Minnesota Academy of Science

Although great horned owls (Bubo virginianus) are often considered permanent residents, data from band returns have shown that movements by this species do occur. In banding activities conducted in central Minnesota from 1967 through 1983, 329 great horned owls were banded and 24 (7.3 percent) recoveries were reported. Twelve of the 24 recoveries (50.0 percent) were made 15 kilometers or more from where the individuals were banded. Five of these recoveries ( 41.7 percent) were to the southeast. Of 23 owls recovered dead, eight (34 .8 percent) were reported only as "found dead," seven (30.4 percent) were found near highways …


Summary Account Of The Carolina Parakeet In Arkansas, Daniel Mckinley, Douglas A. James Jan 1984

Summary Account Of The Carolina Parakeet In Arkansas, Daniel Mckinley, Douglas A. James

Journal of the Arkansas Academy of Science

The extinct Carolina Parakeet (Conuropsis carolinensis) once was part of the Arkansas avifauna. The first two reports of the species in what is now Arkansas were made in 1673 and 1718 by early French explorers. The remaining records are from the 1800s when parakeets were found in nearly all parts of the state, often in abundance. The last literature reference for the species still definitely occurring in Arkansas pertains to birds present in the summer of 1885 along the White River at Newport


The Secretive Silvereyes, I J. Rooke Jan 1984

The Secretive Silvereyes, I J. Rooke

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

Durinf the past five years the agricultural Protection Board, in co-operation with scientists from CSIRO's Division of Wildlife Research and the University of Western Australia, had studied the biology and control of the silvereye in the South-West of Western Asustralia. The project was partially funded by a voluntary levy on vignerons in the Margaret River and Mt Barker areas.

The first part of the study investigated the bird's bioloogy - its food requirements, reproductive rate, how it interacted with other birds and its seasonal movements, It was hoped that this knowledge would help develop effective techniques for either controlling the …

A Closer Look At Parrots As Pests, John L. Long Jan 1984

A Closer Look At Parrots As Pests, John L. Long

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

Small parrots have been attacking fruit and grain crops in the south of Western Australia at least since agriculture expanded into their native habitats in the early 1900s. The parrots are capable of quickly adapting to new situations so it is not surprising that they have eaten crops.

It is not known whether parrot numbers have increased since European settlement began, but this appears likely. The present landscape of islands of uncleared country interspersed with areas of agriculture appears to favour the survival of the red-capped parrot, western rosella and the Port Lincoln parrot. These species were investigated during a …


Keeping Starlings Out Of W.A, John L. Long Jan 1984

Keeping Starlings Out Of W.A, John L. Long

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

In Europe and North America huge flocks of starlings cause millions of dollars worth of damage to grain and fruit crops each year and large sums of money are spent trying to control them.

Starlings were introduced into australia in the late 1890s when more than 200 birds were released near Melbourne. They are now well established over much of eastern Australia, ranging from central Queensland, south to Tasmania and along the Great Australian Bight to the South Australian-Western Australian border, occasionally crossing it and sometimes moving as far west as the Esperance region on the south coast.

Some people …

Seasonal Lekking Behavior Of The Greater Prairie-Chicken In Illinois, Scott A. Simpson Jan 1984

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 …


An Analysis Of The Representation Of Memorial Events In Pigeon Short-Term Memory, Sharon Musgrave Jan 1984

An Analysis Of The Representation Of Memorial Events In Pigeon Short-Term Memory, Sharon Musgrave

Theses and Dissertations (Comprehensive)

There is evidence to suggest that pigeons will actively encode information on delayed matching-to-sample (DMTS) tasks either by maintaining a representation of the sample stimulus during the retention interval (retrospective processing) or by maintaining a representation of the response decision in anticipation of the upcoming comparison stimuli (prospective processing). The following experiments were conducted to determine whether processing in DMTS is retrospective or prospective in nature. Using a paradigm developed by Stonebraker (1981), pigeons were simultaneously trained on two types of tasks: identity and symbolic matching. Only one set of sample stimuli was used and followed by either the symbolic …

Breeding Birds In Cedar Stands In The Great Dismal Swamp, Karen A. Terwilliger, Robert K. Rose Jan 1984

Breeding Birds In Cedar Stands In The Great Dismal Swamp, Karen A. Terwilliger, Robert K. Rose

Biological Sciences Faculty Publications

The Great Dismal Swamp located in the coastal plain on the Virginia- North Carolina border, has long been recognized as a vegetationally distinctive region with many unusual geological and biological features. Formerly at least twice the currently estimated size of 85,000 hectares (Carter 1979), the Great Dismal Swamp is still shrinking because of a dropping water table caused by more than 200 years of logging, ditching, and other human activities. In 1973, the Union Camp Corporation donated a 19,871-hectare tract located near Suffolk, Virginia. to The Nature Conservancy, which transferred the land to the U.S. Fish and Wildlife Service. This …


Alcataenia Campylacantha (Krabbe, 1869) From Pigeon Guillemots, Cepphus Columba Pallas, And Black Guillemots, Cepphus Grylle (Linnaeus), And Alcataenia Sp. Indet. (Cestoda: Dilepididae) From Kittlitz's Murrelets, Brachyramphus Brevirostris (Vigors) In Alaska, Eric P. Hoberg Jan 1984

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Alcataenia campylacantha (Krabbe, 1869) is redescribed and reported for the first time from pigeon guillemots, Cepphus columba Pallas, in Alaska. Specimens of this cestode were also found in black guillemots, Cepphus grylle (Linnaeus) at Point Barrow, Alaska. There were no substantial differences in morphological characters between populations of this cestode from the North Atlantic and North Pacific basins. Additionally, Alcataenia sp. indet. is reported, with a partial description, from Kittlitz's murrelets, Brachyramphus brevirostris (Vigors), in Alaska. This constitutes the first record of dilepidid cestodes from birds of the genus Brachyramphus Brandt.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Alcataenia longicervica sp. n. (Cestoda: Dilepididae) is described from murres, Uria spp., in Alaska and other localities in the Pacific basin. From Alcataenia armillaris (Rudolphi, 1810), which it most closely resembles, A. longicervica is distinguished by larger size of organs (cirrus sac, vitelline gland, and seminal receptacle), greater number of testes, and extremely long neck. In specimens of A. longicervica there are 22-27 rostellar hooks distributed in two rows. Hooks in the anterior row measure 41-49 μm in length while those in the posterior are 38-48 μm. Two species of Alcataenia, A. armillaris and A. meinertzhageni (Baer, 1956), both …


Trematode Parasites Of Marine Birds In Antarctica: The Distribution Of Gymnophallus Deliciosus (Olsson 1893), Eric P. Hoberg Jan 1984

Trematode Parasites Of Marine Birds In Antarctica: The Distribution Of Gymnophallus Deliciosus (Olsson 1893), Eric P. Hoberg

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During continuing studies of avian helminths at Palmer Station, Antarctica (Hoberg 1983) trematodes were found as parasites only of charadriiform birds. Digeneans were not represented in extensive collections (including several thousand specimens of helminths) from spheniscids, procellariids, and phalacrocoracids.

The pattern of distribution of trematodes in marine birds in Antarctica is influenced by the availability of suitable intermediate hosts (mollusca) and the foraging behavior of potential final hosts. Littoral environments near Palmer are structurally simple and of low diversity due to ice scouring. The limpet, Nacella polaris, is the dominant intertidal invertebrate and one of the few molluscs that …


Angularella Audubonensis Sp. N. (Dilepididae) And Other Cestodes Of Cliff Swallows In Colorado, Jeffrey D. Stamper, Gerald D. Schmidt Jan 1984

Angularella Audubonensis Sp. N. (Dilepididae) And Other Cestodes Of Cliff Swallows In Colorado, Jeffrey D. Stamper, Gerald D. Schmidt

Harold W. Manter Laboratory of Parasitology: Faculty Publications

One hundred forty-five cliff swallows, Petrochelidon pyrrhonota, were examined for cestodes in two separate surveys in Weld County, Colorado. Seven species representing four genera were found. Angularella audubonensis sp. n. is differentiated by the small size of the rostellar hooks (8.4-13.5 μm) and the medial relationship of the cirrus pouch to the osmoregulatory canals. Other species collected were Angularella beema, Anonchotaenia globata, Mayhewia ababili, Vitta magniuncinata, Vitta parvirostris and Vitta riparia. Seven new hosts and geographic distribution records were established for Colorado, and six new records were determined for North America.


Operant Conditioning In The Psittacine, Amazona Amazonica, Gloria J. Nadolski Jan 1984

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 …

Nebraska Bird Review

The Chuck-will's widow (Caprimulgus carolinensis) is considered a highly local but regular migrant and presumed summer resident in Nebraska. Although it is known to breed in Kansas and Oklahoma, there were no nest records for Nebraska (Johnsgard, 1980). Egg dates for Kansas range from 21 April to 31 May (Johnsgard, 1979). On 4 June 1983 a Chuck-will's widow's nest with 2 eggs was discovered in a bur oak (Quercus macrocarpa)–red cedar (Juniperus virginiana) woodland at Camp Merrill, Saunders Co. (Sec 29 T17N RSW), approximately 6 miles southeast of Linwood (Janett Waever, pers. comm.) The …


Aspects Of The Nesting Ecology Of Least Terns And Piping Plovers In Central Nebraska, Craig A. Faanes Dec 1983

Aspects Of The Nesting Ecology Of Least Terns And Piping Plovers In Central Nebraska, Craig A. Faanes

Papers in Ornithology

Breeding habitat of the least tern is made up primarily of coastal beaches and inland river sandbars. Populations of the interior (Sterna antillarum athalassos) and east coast (S. a. antillarum) subspecies are now declining (Marshall et al. 1975, Duffy 1977, Jernigan et al. 1978) and the western subspecies (S. a. browni) is endangered (Wilbur 1974). Although coastal populations have received considerable attention (Wolk 1974, Atwood et al. 1977, Blodgett 1978), little research has been conducted on the interior race (Hardy 1957, Downing 1975).

The piping plover inhabits river sandbars and sand beaches and, like …

Breeding Status Of Selected Bird Species In The Niobrara Valley Preserve Area, Nebraska, Michael J. Mossman, Mark A. Brogie Jun 1983

Breeding Status Of Selected Bird Species In The Niobrara Valley Preserve Area, Nebraska, Michael J. Mossman, Mark A. Brogie

Nebraska Bird Review

INTRODUCTION

The Niobrara Valley Preserve is located in north-central Nebraska and includes a variety of relatively undisturbed grassland, woodland, and wetland habitats. The diversity of habitats, in conjunction with the area's central geographic location near the 100th meridian, results in a diverse avifauna with many species and subspecies occurring at or near the western, eastern, southern, or northern edge of their breeding ranges. Several pairs of sibling species and subspecies are found here within their narrow band of sympatry. The breeding list of the Preserve and environs includes at least 105 species (Brogie and Mossman 1983), several of which are …
