An overview of published studies of the intake rates (mg AFDM s−1) of free-living, over-wintering European oystercatchers consuming native bivalve species: M. edulis (black); C. edule (open); S. plana (dark grey); and M. balthica (pale grey). Frequencies refer to the number of independent values of intake rate presented in the source paper (Zwarts et al. 1996a). The arrow denotes the value of the mean intake rate achieved by birds specializing on Manila clams (n=27) in this study (2.02 mg AFDM s−1 (95% CI 1.673–2.367 mg AFDM s−1)).
