In bird species, nest parasitism, in which female birds lay eggs in other individuals' nests, is often observed. If the host is the same species as that of parasite, it is called 'intraspecific nest parasitism', Otherwise it is called 'interspecific nest parasitism'. About 1% of all bird species have been observed to be interspecific parasites, although the percentage seems to be much higher in recent reports. The evolutionary process of nest parasitism is an important issue, although it is difficult to study in the field or the laboratory. Therefore, the evolution of parasitism has been studied by mathematical analysis, which is very useful for clarifying of the evolutionary processes and conditions of nest parasitism. In this paper, factors affecting the evolution of parasitism are discussed, and mathematical studies of the relationship between these factors and the evolutionary processes are reviewed.
