Other possible breeding areas may extend the second range east to the lower …


Cranes Of The World: 3. Vocalizations, Paul A. Johnsgard Jan 1983

Cranes Of The World: 3. Vocalizations, Paul A. Johnsgard

Cranes of the World by Paul A. Johnsgard

Of all avian sounds, few have the power to catch the human imagination and thrill the senses as much as does the bugling of a flock of distant cranes. Leopold (1949) referred to the progressively louder sounds of an approaching flock of sandhill cranes as “a tinkling of little bells,” the “baying of some sweet-throated hound,” and finally as “a pandemonium of trumpets, rattles, croaks, and cries.” The Greeks called it “iangling,” and most recent writers have compared the calls of typical Grus cranes to trumpets or bugles. In doing so, they have inadvertently drawn attention to the similarity of …


Cranes Of The World: Wattled Crane (Bugeranus Carunculatus), Paul A. Johnsgard Jan 1983

Cranes Of The World: Wattled Crane (Bugeranus Carunculatus), Paul A. Johnsgard

Also …


Hybridization & Zoogeographic Patterns In Pheasants, Paul A. Johnsgard Jan 1983

Hybridization & Zoogeographic Patterns In Pheasants, Paul A. Johnsgard

Paul Johnsgard Collection

A review of interspecific pheasant hybrids as reported in the literature reveals a relatively high rate of hybridization in captivity but a low rate of hybridization in the wild. All of the 91 known hybrid combinations have been reported from captivity, and three of these combinations have also been reported from the wild. All of the latter involve species pairs of known close relationships (red and gray junglefowl, kalij and silver pheasant, and white and blue eared pheasant), suggesting that reproductive isolating mechanisms in the pheasants are much more effective under natural conditions than are those of grouse, a group …

Scaring Of Carrion Crows (Corvus Corone Corone) By Species-Specific Distress Calls And Suspended Bodies Of Dead Crows, Luzia Naef-Daenzer Jan 1983

Scaring Of Carrion Crows (Corvus Corone Corone) By Species-Specific Distress Calls And Suspended Bodies Of Dead Crows, Luzia Naef-Daenzer

Bird Control Seminars Proceedings

In Switzerland, carrion crows can cause considerable damage to sprouting corn fields when feeding on the germinated corn. I tried to evaluate a method to prevent these damages. The use of species-specific distress calls, for the first time described by Frings and Jumber (1954), seemed to be the most promising method. Agronomes and biologists have applied it in field studies to several different bird species causing damage in agriculture and on airports (e.g., Gramet, 1962; Brough, 1968). However, the literature either describes single actions or several different scaring devices being used together. To be able to judge the method, quantitative …

Mate And Nest-Site Fidelity Among Tree Swallows In Central Minnesota, Carol Fiedler, Alfred Grewe Jan 1983

Mate And Nest-Site Fidelity Among Tree Swallows In Central Minnesota, Carol Fiedler, Alfred Grewe

Journal of the Minnesota Academy of Science

Movement of tree swallows (lridoprocne bicolor) between successive breeding sites and pair bond formation was analyzed from data collected between 1965 and 1978 in central Minnesota. A lasting pair bond did not seem to exist between breeding pairs. The majority of the breeding pairs were found to separate after one year. Those that did remate usually did so in the same or an adjacent nest box. Age and reproductive success did not appear to affect whether a pair remated or divorced. Movement of the male and female the year following their mating did seem to be a factor. Males tended …


Success Of Wild-Trapped Compared To Captivity-Raised Birds In Restoring Wild Turkey Populations To Northwestern Arkansas, Douglas A. James, L. Glen Fooks, John R. Preston Jan 1983

Success Of Wild-Trapped Compared To Captivity-Raised Birds In Restoring Wild Turkey Populations To Northwestern Arkansas, Douglas A. James, L. Glen Fooks, John R. Preston

Journal of the Arkansas Academy of Science

Reintroduction of wild turkeys into northwestern Arkansas was studied at 10 release sites in the late 1950's. Native birds trapped in southern Arkansas were released at five study areas, and birds from wild Pennsylvania stock reared in captivity were released in five other areas. Although both types of turkeys reproduced, most populations of captivity-raised turkeys decreased sharply whereas all populations of wild-trapped birds exhibited marked increases. Range extension averaged nearly 2.5 miles per year in expanding wild-trapped populations. Captivity-raised birds were comparatively tame and often were found near human habitation. Current expanding turkey populations in the Arkansas Ozarks undoubtedly are …


Optimal Foraging Theory And The Psychology Of Learning, Alan Kamil Jan 1983

Optimal Foraging Theory And The Psychology Of Learning, Alan Kamil

Avian Cognition Papers

The development of optimization theory has made important contributions to the study of animal behavior. But the optimization approach needs to be integrated with other methods of ethology and psychology. For example, the ability to learn is an important component of efficient foraging behavior in many species, and the psychology of animal learning could contribute substantially to testing and extending the predictions of optimal foraging theory.


Habitat Selection Related To Resource Availability Among Cavity-Nesting Birds, Timothy Brush Jan 1983

Habitat Selection Related To Resource Availability Among Cavity-Nesting Birds, Timothy Brush

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

Variation in snag species and abundance appeared to explain most of the habitat selection patterns observed in five cavity-nesting riparian species over a three-year period. All species except Ash-throated Flycatchers were most common in areas with cottonwood or willow snags, which have relatively soft wood and are preferred nest sites. Classification of habitats on the basis of nest-site characteristics was useful and should be considered in other habitat selection studies.

A Checklist Of The Birds Of Mormon Island Crane Meadows, Gary R. Lingle, Miriam A. Hay Jun 1982

A Checklist Of The Birds Of Mormon Island Crane Meadows, Gary R. Lingle, Miriam A. Hay

Nebraska Bird Review

Mormon Island Crane Meadows (MICM) was purchased in December 1979 through a cooperative effort of The Nature Conservancy and The Platte River Whooping Crane Critical Habitat Maintenance Trust. This 2,000 acre preserve provides excellent habitat for spring staging migratory water birds and numerous species of other wildlife, In order to determine sound management practices for the area it was necessary to conduct an intensive inventory of the flora and fauna occurring there. This checklist represents the results of the bird inventory.

Notes on the occurrence of avifauna observed on MICM were recorded from 24 March 1980 to 28 July 1981. …

Whooper Recount: A Close Look At These Endangered Cranes Reveals That, While Their Numbers Are Increasing, Their Rate Of Increase Is Actually Declining, Paul A. Johnsgard Feb 1982

Whooper Recount: A Close Look At These Endangered Cranes Reveals That, While Their Numbers Are Increasing, Their Rate Of Increase Is Actually Declining, Paul A. Johnsgard

Papers in Ornithology

I have assembled figures for the 43-year period from 1938 through 1980, and have subjected them to various kinds of analysis. During this period, 220 young and 1,437 postjuvenile birds have appeared on the wintering grounds. This works out to an annual recruitment rate of 13.3 percent. (This is not exactly the same as the birthrate, of course, since the loss of eggs, chicks, and juveniles prior to arrival at Aransas is excluded.) The recruitment rate provides an estimate of the rate of maximum annual population increase. One hundred fifty-four birds that had been counted in any given year failed …


Minnesota Colonial Waterbird Nesting Site Inventory, Carrol L. Henderson Jan 1982

Minnesota Colonial Waterbird Nesting Site Inventory, Carrol L. Henderson

Journal of the Minnesota Academy of Science

Since colonial nesting waterbirds comprise an Important portion of Minnesota's avifauna, it Is important to establish an accurate Inventory of their nesting areas. Knowledge of the status of these species can be used to assess the level of the state's environmental quality. The inventory is also useful in aiding planners and developers so that undesirable impacts on colonies can be avoided or minimized. The Nongame Wildlife Program in the Department of Natural Resources has identified 239 colony sites in Minnesota which are occupied by 16 species. This Inventory process is the first step necessary to carry out future research, management, …


Maps Of Distribution And Abundance Of Selected Species Of Birds On Uncultivated Native Upland Grasslands And Shrubsteppe In The Northern Great Plains, Harold A. Kantrud Jan 1982

Maps Of Distribution And Abundance Of Selected Species Of Birds On Uncultivated Native Upland Grasslands And Shrubsteppe In The Northern Great Plains, Harold A. Kantrud

United States Fish and Wildlife Service: Publications

Many areas of the northern Great Plains (Fenneman 1931) remain poorly known ornithologically. Knowledge of species distribution in portions of this vast area has been advanced by recent State birds books (Stewart 1975; South Dakota Ornithologists' Union 1978) but many voids remain. Especially desirable for biologists and land managers is information concerning the relative abundance of plant and animal species over large land areas. This information can only be obtained from extensive surveys of the biota. The field of community ecology has been severely hampered by lack of information on species abundance (Dice 1930; Cain 1947; Partch 1962; Udvardy 1963). …


The Red-Tailed Hawk On Sauvie Island, Oregon, Kevin J. Lien Jan 1982

The Red-Tailed Hawk On Sauvie Island, Oregon, Kevin J. Lien

Dissertations and Theses

A study was undertaken to determine the abundance, distribution, perching heights, diets and territory sizes of Red-Tailed Hawks on Sauvie Island, Oregon. Sauvie Island supported a large wintering population of non-territorial Red-Tailed Hawks. The establishment of territories began around 10 January. Average perch height was found to be 14.2 m. Average perch height increased from fall to spring, corresponding-to the onset of the breeding season and to the onset of egg-laying and incubation. Voles (Microtus spp.) were the principal prey year-round, though waterfowl were more important in terms of biomass in the winter and early spring. Territory sizes on the …


Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf Jan 1982

Spatial Learning As An Adaptation In Hummingbirds, Susan Cole, F. Reed Hainsworth, Alan Kamil, Terre Mercier, Larry L. Wolf

Avian Cognition Papers

An ecological approach based on food distribution suggests that hummingbirds should more easily learn to visit a flower in a new location than to learn to return to a flower in a position just visited, for a food reward. Experimental results support this hypothesis as well as the general view that differences in learning within and among species represent adaptations.


Teton Wildlife: Observations By A Naturalist, Paul A. Johnsgard Jan 1982

Teton Wildlife: Observations By A Naturalist, Paul A. Johnsgard

Papers in Ornithology

The diversity of wildlife in Grand Teton National Park and its environs draws millions to the valley of Jackson Hole every year, but few are the visitors who are able to observe individual species over the course of several seasons. Paul Johnsgard, a noted naturalist who has written many books on the waterfowl of the world, here integrates his own observations with those who have studied Teton wildlife in the past. The result is a compassionate, simple reconstruction of the lives of a few individuals from spring through early autumn.

Teton Wildlife describes the migration of a herd of antelope …


Etho-Ecological Apects Of Hybridization In The Tetraonidae, Paul A. Johnsgard Jan 1982

Etho-Ecological Apects Of Hybridization In The Tetraonidae, Paul A. Johnsgard

Paul Johnsgard Collection

A review of records of intrafamilial hybridization in the Tetraonidae indicates that at least half of the potential natural hybrid combinations that could occur in this family on the basis of known distribution patterns actually have been reported at least once. These include 15 interspecific hybridization combinations that involve 12 species and all of the genera currently recognized by taxonomists. The three most commonly reported hybrid combinations all involve lek-forming species of grouse as parental types, while the remaining 12 combinations are all considerably rarer and involve lek-forming parental species in 7 cases, promiscuous but solitary species in 6 cases, …

Key To Trematodes Reported In Waterfowl, Malcolm Edwin Mcdonald Sep 1981

Key To Trematodes Reported In Waterfowl, Malcolm Edwin Mcdonald

Harold W. Manter Laboratory of Parasitology: Library Materials

This key is the second in a series for identification of the helminths reported in waterfowl (Family Anatidae, Order Anseriformes). The first was a key to nematodes (McDonald 1974).

The trematodes show the greatest variety of forms among the helminth parasites of waterfowl, including over half of all species reported; sometimes this group also includes the greatest part of the worms in a single bird. Over 500 species of trematodes have been reported in waterfowl. Almost all of these have been included in the present set of keys; it was not possible, however, to obtain the descriptions of a few …
