Abstract

In an experimental study of sexual dimorphism in plumage coloration in the house sparrow, Passer domesticus, skin grafts were exchanged between nestlings on the first to sixth day after hatching. Before fledging, the young birds were moved from the nest to cages and kept for several weeks for observation of the coloration of feathers produced by host and graft skin. The adult feathers that developed on grafted skin at the postjuvenal molt corresponded to those of the donor, regardless of the sex of the host.

A gender difference in motor activity level (AL) is well established for children, but questions about the existence and nature of an infant sex difference remain. To assess these questions, we applied meta-analytic procedures to summarize 46 infancy studies comprising 78 male -female motor activity
