Fitting trials of Fisher's logarithmic series and the truncated discrete lognormal distribution proposed by PRESTON were made to the bird survey records obtained in the eastern Chugoku mountain range. Twenty-six series of species abundance data were tallied from the records by survey area, breeding season, non-breeding season, belt transect census, station census, and the difference of vegetation. Excepting some series of data, both mathematical models well described the almost all relations between the number of species and the number of individuals. If the survey work was conducted satisfactorily, the parameters of the fitted mathematical models would be useful indicators of natural environmental situation.
