The Ecology Of Foraging Behavior: Implications For Animal Learning And Memory, Alan Kamil, Herbert L. Roitblat
The Ecology Of Foraging Behavior: Implications For Animal Learning And Memory, Alan Kamil, Herbert L. Roitblat
Avian Cognition Papers
In his recent Annual Review of Psychology article, Snowdon (1983) discussed the synthesis of ethology and comparative psychology. A similar synthesis of behavioral ecology and animal learning is beginning to take place. This article reviews developments in the behavioral ecology and ethology of foraging behavior relevant to psychological research on animal learning. The psychological literature shows that animals possess a wide range of learning abilities, including “simple” classical and operant conditioning; they acquire spatial, nonspatial, and temporal discriminations; they exhibit various forms of rule learning (e.g. matching-to-sample and learning set), and may even in certain senses learn language. Why does …
Bobwhite Thesaurus, Thomas G. Scott
Bobwhite Thesaurus, Thomas G. Scott
Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials
The Bobwhite Thesaurus was assembled with the belief that it would make the voluminous literature more accessible. Publications on the bobwhite have become so numerous and have been published in so many different places that today's bobwhite researcher is seldom able to conduct the library search required to unearth all pertinent material. This results in failure to acknowledge and use prior findings.
An effort has been made to seek out and index all publications issued prior to 1983 that contain information on the bobwhite. All publications found have been included irrespective of their apparent worth excepting anonymous papers. Publications which …

Optimal Foraging Theory And The Psychology Of Learning, Alan Kamil
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.

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.

First paragraph:
Die Landschaften der Mongolei sind arm an Reptilien- und Amphibienarten. Dieser Umstand mag die Frage aufwerfen, ob herpetologische Untersuchungen in Beschränkung auf das Territorium der MVR eine nennenswerte Perspektive haben könnten, nachdem Artenspektrum und Verbteitung der Species annähernd vollständig erkundet sind. Ein Herpetologe wird zweifellos für seine Arbeit auch in diesem Land eine Zukunft sehen, doch muß wohl von vornherein eingestanden werden, daß das Volumen der Probleme dieses Faches hinter denen der übrigen Disziplinen der Vertebratenzoologie und der Entomologie in einem bescheidenerem Rahmen verbleibt. Dies gilt sowohl im rein wissenschaftlichen als erst recht auch im angewandten Bereich ihrer …

Habitat Use By Native Gambel' S And Scaled Quail And Released Masked Bobwhite Quail In Southern Arizona, John G. Goodwin Jr., C. Roger Hungerford
Habitat Use By Native Gambel' S And Scaled Quail And Released Masked Bobwhite Quail In Southern Arizona, John G. Goodwin Jr., C. Roger Hungerford
Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials
Populations of both Gambel's and scaled quail surveyed in southern Arizona declined by 60% from October 1975 to June 1976. Masked bobwhite population density increased during the study because of additional releases, but survival patterns are uncertain. Raptors were efficient quail predators.
Gambel's quail were associated with a dense overstory of mesquite, hackberry, wolfberry, and catclaw. Understory species varied in density and appeared less essential to good habitat. Scaled quail preferred open, grass-shrub habitat, with few of the plants over 6 feet tall. Masked bobwhite selected dense, grass-weed habitat, with pigweed a characteristic species.
Green vegetation and insects were seasonally …
Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil
Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil
Avian Cognition Papers
Blue jays learned to respond differentially to the presence or absence of Catocala moths in slides. This detection of the moths by the jays was affected by the background upon which the moth was placed and its body orientation, thus providing an objective measure of crypticity. These procedures are useful for the study of visual detection of prey.

Proceedings Of Perdix I: Hungarian Partridge Workshop, The Wildlife Society, Central Mountains And Plains Section, The Wildlife Society, North Dakota Chapter, North Dakota Game And Fish Department
Galliformes Specialist Group and Affiliated Societies: Conference Proceedings
Perdix I has succeeded in its major objective of bringing Hungarian partridge research and management people together in one place for introduction to one another and for a mutually beneficial exchange of information. A major communications bridge has been gapped by the informalization that occurs with the development of face-to-face relationships, a realization of how similar everyone's technical problems are, and an expression of concern regarding the need to develop work plans and guidelines to help direct future research and management by avoiding unnecessary duplication that often occurs with poor communications. As regards communications, it is refreshing to know that …
Bobwhite Quail Food Habits In The Southeastern United States With A Seed Key To Important Foods, J. Larry Landers, A. Sydney Johnson
Bobwhite Quail Food Habits In The Southeastern United States With A Seed Key To Important Foods, J. Larry Landers, A. Sydney Johnson
Galliformes Specialist Group and Affiliated Societies: Reports and Other Materials
A search of the literature revealed 27 studies of food habits of bobwhite quail in the southeastern United States. These include data from nearly 20 ,000 birds. In this publication all seed foods reported in these studies are listed and evaluated, and a key to important species is included. Over 650 seed foods are listed, and volume and frequency classes are given for each seed food as reported in each study. Only 78 foods comprised 1 percent or more of the food volume in one or more studies. The 45 most important foods are ranked for each physiographic province. The …
