Verhalten des Paares, der Familie, der Koloniemitglieder und der Individuen einer Schlafgesellschaft.

The film presents aspects of the social behaviour of the House Sparrow within different intraspecific social groups: pair, familiy, family group, and flock. Females dominate males when feedings as well as when sand or dust bathing. The juvenile members of the families are gradually integrated into the flock afterwards. The different social grouping within the species have different functions.
