Evolutionary Advantage

AbstractTheory predicts that individuals behave altruistically towards their relatives. Hence, some form of kin recognition is useful for individuals to optimize their behaviour. In species displaying bi-parental care and subject to extra-pair matings, kin recognition theoretically allows cuckolded fathers to reduce their parental investment, and thus optimize their fitness, but whether this is possible remains unclear in birds. This study investigates the ability of male sparrows to recognize their own chicks, using a large cross-foster experiment, parental care as an indicator and House Sparrows (Passer domesticus) as a model organism. We cross-fostered chicks after hatching, and then expected that fathers would show a decrease in their parental efforts when tending to a clutch of unrelated offspring. However, there was no significant effect of relatedness on provisioning rates. This suggests that sparrows may not be capable of kin recognition, or at least do not display kin discrimination despite its apparent evolutionary advantage.

Trade Offs

Biparental care systems are a valuable model to examine conflict, cooperation, and coordination between unrelated individuals, as the product of the interactions between the parents influences the fitness of both individuals. A common experimental technique for testing coordinated responses to changes in the costs of parental care is to temporarily handicap one parent, inducing a higher cost of providing care. However, dissimilarity in experimental designs of these studies has hindered interspecific comparisons of the patterns of cost distribution between parents and offspring. Here we apply a comparative experimental approach by handicapping a parent at nests of five bird species using the same experimental treatment. In some species, a decrease in care by a handicapped parent was compensated by its partner, while in others the increased costs of care were shunted to the offspring. Parental responses to an increased cost of care primarily depended on the total duration of care that offspring require. However, life history pace (i.e., adult survival and fecundity) did not influence parental decisions when faced with a higher cost of caring. Our study highlights that a greater attention to intergenerational trade-offs is warranted, particularly in species with a large burden of parental care. Moreover, we demonstrate that parental care decisions may be weighed more against physiological workload constraints than against future prospects of reproduction, supporting evidence that avian species may devote comparable amounts of energy into survival, regardless of life history strategy.

The Way

The following case presents the way that overtly oedipal identification in a young woman covered failure in early parental care and discontent between her parents. The case was presented by Li Yanling to her supervision group, and the commentary and elaboration have been gathered from comments from the entire group of advanced supervisees, all of whom were discussion group leaders in the Beijing Continuous Program in Psychoanalytic Couple and Family Therapy.
