Description	A method that was based on non-invasive sampling of genetic material was used to determine the rates of extra-pair paternity (EPP) and conspecific brood parasitism (CBP) in mallards. Using 8 microsatelite loci, extra-pair offspring were detected in 48% of nests and accounted for 9.3% of all offspring. In addition, 10.1% of the offspring were confirmed to result from CBP, and 24% of all nests contained at least 1 offspring from CBP. Rates of conspecific nest parasitism were higher than those of related species, which might have been due to higher breeding densities at our study site. The incidence of EPP was distributed randomly throughout the population, indicating that variations in pre-copulatory (e.g. female choice, mate guarding) or post-copulatory processes do not affect the distribution of EPP among breeding pairs markedly. The occurrence of CBP and EPP was unaffected by the timing of the breeding attempt or breeding synchrony.
