Although much research has been devoted to studying sex differences In functioning (e.g., Maccoby and Jacklin 1974), most efforts have been directed toward documenting or elucidating the proximate causes of sex differences. Few attempts have been made, however, to explain the ultimate causes of these differences or the selective pressures that have led to the development or psychological differences between males and females [for exception see Symons (1979) and Daly and Wilson (1983)]. Toward this end of blending psychology with evolutionary theory we develop what we call the " primary caretaker hypothesis," which predicts that the sex that through evolutionary …

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 …

Mammals, Birds, And Butterflies At Sodium Sources In Northern Ontario Forests, D. Fraser
Feeding Behavior Collection
Wildlife seen at natural sodium-rich springs and at roadside pools contaminated by highway de-icing salt in northern Ontario included two species of wild ungulates, one species of rodent, three species of birds, and two species of butterflies. The three birds were finches of the sub-family Carduelinae, noted for feeding almost exclusively on plant material. The mammalian species were also herbivorous. Apart from Porcupines (Erethizon dorsaturn), small mammals were rarely seen at the saltwater locations, perhaps because of their apparent preference to ingest salt in solid form rather than in water.
