The chicks of cavity nest birds, among them the chicks of tits, are  relatively well protected from predators but in their nests a variety of parasites may be found. The nest parasites, whose activities are favoured by the temperature and air humidity of the cavity, may influence the life of adults as well as of the growing chicks significantly by sucking blood or feeding on feathers.
