Article summary

A census of breeding birds was taken in a smal wood by both Capture-Recapture and Mapping methods. Four specialists analysed the maps and provided estimations of the number of territorial males. These results were compared with C.R. estimates (Table 1). There were important discrepancies between the results obtained with the two methods as well as those obtained by each specialist. Consequently, none of these estimations can be considered as totally reliable.
