  Title Grouped sequential exploitation of food patches in a flock feeder, the feral pigeon Type Journal Article
  Year 1985 Publication Behavioural Processes Abbreviated Journal Behav. Process.  
  Volume 11 Issue 1 Pages 39-52  
  Keywords  
  Abstract Feral and laboratory flocks of rock doves ( ) show a pattern of grouped sequential exploitation when simultaneously presented with two dispersed, depleting patches of seed. This behavior contrasts with the ideal free distribution pattern shown when patches are small and concentrated. Grouped sequential exploitation consists of two phases: all pigeons first land together and feed at one patch, then leave one by one for the other patch. Departure times of individuals for the second patch are correlated with feeding rate at patch 1, which is in turn correlated with position in the dominance hierarchy. The decision to switch from patch 1 to patch 2 improves individual feeding rates in all cases, but is done slightly later than it should according to optimal foraging theory.

  Title Self-control revisited: Some factors that affect autoshaped responding Type Journal Article
  Year 1985 Publication Behavioural Processes Abbreviated Journal Behav. Process.  
  Volume 10 Issue 1-2 Pages 77-85  
  Keywords  
  Abstract Pigeons were exposed to autoshaping procedures under which 50% of red key illuminations were followed by 9-sec food deliveries, and 50% of blue key illuminations were followed by 3-sec food deliveries. When all key illuminations were 6 sec, pigeons preferred the red stimulus. Subsequent manipulations demonstrated that preference could be shifted to the blue stimulus by either increasing the duration of the red stimulus or imposing a delay interval between the offset of that stimulus and food delivery. A final experiment demonstrated that, in two of three subjects, preference for key illuminations associated with longer, but delayed, food deliveries generally increased as the duration of all key illuminations was lengthened. These results, obtained under conditions where keypecking had no programmed consequences, are similar to those previously observed under procedures involving a positive response-food dependency.

  Abstract This is the introductory paper to a series on the ecology of arboviruses in Argentina. Epizootics of equine encephalitis have occurred since at least 1908, principally in the Pampa and Espinal biogeographic zones, with significant economic losses; human cases of encephalitis have been rare or absent. Both western equine and eastern equine encephalitis viruses have been isolated from horses during these epizootics, but the mosquitoes responsible for transmission have not been identified. A number of isolations of Venezuelan equine encephalitis (VEE) virus were reported between 1936 and 1958 in Argentina, but the validity of these findings has been seriously questioned. Nevertheless, serological evidence exists for human infections with a member of the VEE virus complex. Serological surveys conducted in the 1960s indicate a high prevalence of infection of humans and domestic animals with St. Louis encephalitis (SLE), and 2 SLE virus strains have been isolated from rodents. Human disease, however, has rarely been associated with SLE infection. Only 7 isolations of other arboviruses have been described (3 of Maguari, 1 of Aura, 2 of Una, and 1 of an untyped Bunyamwera group virus). In 1977, we began longitudinal field studies in Santa Fe Province, the epicenter of previous equine epizootics, and in 1980 we extended these studies to Chaco and Corrientes provinces. The study sites are described in this paper.

  Title Different Observational Learning Capacity in Juvenile and Adult Individuals of Congeneric Bird Species Type Journal Article
  Year 1985 Publication Zeitschrift für Tierpsychologie Abbreviated Journal Z. Tierpsychol.  
  Volume 69 Issue 4 Pages 293-304  
  Keywords  
  Abstract Abstract and Summary: Since the adaptive significance of social organization is emphasized diversely in both anti-predator behaviour and food searching of birds, measures and comparisons of observational learning capacity of various species are needed. Four different experimental situations were built up for juvenile and adult individuals of tits (Parus major, P. caeruleus, P. palustris) and thrushes (Turdus merula, T. philo-melos). The birds learn more easily from conspecifics and learn easily when they already know a previous problem solving situation. The capacity of observational learning of the adult great tits surpasses that of adult blue tits and marsh tits, and that of the adult blackbirds exceeds that of the adult songthrushes. The higher performance of the great tit and blackbird can be related to their greater hemispheric index. The differences in the learning capacity of the naive individuals of the three tit species and that of the two thrush species were not significant. It is suggested, that the higher observational learning of the great tit and blackbird is evolved through maturational processes and can be reflected by their greater adaptability. Zusammenfassung: Lernen durch Nachahmung wurde in vier verschiedenen Situationen mit jungen und alten Individuen von Meisen- (Parus major, P. caeruleus, P. palustris) und Drosselarten (Turdus merula, T. philomelos) untersucht. Die Vögel lernten besser von Artgenossen und lernten leicht, wenn sie vorher bereits eine Problemlösungssituation kannten. Die Lernfähigkeit (durch Nachahmung) alter Kohlmeisen übertraf die alter Blau- und Sumpfmeisen; die Lernfähigkeit alter Amseln übertraf die alter Singdrosseln. Die höhere Leistung der Kohlmeisen und Amseln hängt mit ihrem höheren Hemisphären-Index zusammen. Naive Individuen der Meisen- und Drosselarten zeigten keine signifikanten Unterschiede in ihrer Lernfähigkeit. Es ist anzunehmen, daß die höhere Lernfähigkeit der Kohlmeise und der Amsel im Laufe der Entwicklung durch Reifungsprozesse zustande kommt und sich in ihrer höheren Anpassungsfähig-keit widerspiegelt.

  Title Sustenance and Symbol: Anthropological Studies of Domesticated Animals Type Journal Article
  Year 1985 Publication Annual Review of Anthropology Abbreviated Journal  
  Volume 14 Issue Pages 375-403  
  Keywords  
  Abstract INTRODUCTION Thinking about Animals For nearly as long as anything can be inferred about human cognition, paleoanthropologists and archaeologists believe humans have thought carefully about animals, about the “predominant characteristic” of each animal, and about those “contradictory elements” that make up humankind. This careful thought has had many outcomes, some scientific, others not. Among the scientific outcomes in the 19th century was evolutionary thinking about the causes and consequences of domestication, including Charles Darwin's study (32) of the mechanics of human (artificial) selection of domesticated animal and plant population characteristics. In the 20th century, theoretical refinements and the painstaking collection of empirical data have led to studies of such disparate phenomena as the physical consequences of keeping pets (12); the spread of antibiotic-resistant bacteria as a result of feeding antibiotics to livestock (117); and the evolutionary consequences of milkdrinking (99). Speculation about the origins of human-animal interaction is not the exclusive province of scientists: religions and storytellers alike customarily try to account for the beginnings of human-animal interaction. Genesis does so

  Title Handling time and choice in pigeons Type Journal Article
  Year 1985 Publication Abbreviated Journal J Exp Anal Behav  
  Volume 44 Issue 2 Pages 139-155  
  Keywords  
  Abstract According to optimal foraging theory, animals should prefer food items with the highest ratios of energy intake to handling time. When single items have negligible handling times, one large item should be preferred to a collection of small ones of equivalent total weight. However, when pigeons were offered such a choice on equal concurrent variable-interval schedules in a shuttlebox, they preferred the side offering many small items per reinforcement to that offering one or a few relatively large items. This preference was still evident on concurrent fixed-cumulative-duration schedules in which choosing the alternative with longer handling time substantially lowered the rate of food intake.
