Naturalist Konrad Lorenz found that newborn birds would become emotionally attached to the first moving thing with which they interacted. Imprinting is a product of natural selection, since their first encounter would be their mother in nature. This bond was even found to extend to inanimate objects, such as toy trains or white balls. However, imprinting to an individual that is not their parent can be highly dangerous in the wild.
The parental care behavior of Tilapia mariae, a species of fish, was examined in the Ethiop River, Nigeria and in an aquarium setting. The males of this species show considerably less interest in the guarding of their young in nature, as roughly 20 percent of the time there is only one parent, often the female, defending the nest. However, in aquaria, the male fish attacked intruders more often, likely due to innate hormone differences.
This study consisted of twenty trials with Capuchin Monkeys in which they were presented with a relatively difficult foraging challenge. The apes were separated into social groups and individuals, and the social subjects were three times more likely to successfully learn the foraging techniques. In-group conformity and learning seem to be promising effects of imitation and emulation in groups of Capuchin monkeys.
The ability of Whooping Cranes to remain on a migration route with minimal deviation grew steadily to the age of five. This unique research studied long-term, learned social behavior in the species, as opposed to classical research on short-lived Songbirds, and it found that older cranes successfully taught newborns migration patterns.
