Mean parameter estimates for the single species functional response (middle column of table) and multi-species functional response (RHS column) fitted to the hen-harrier data set. The parameters are a, the encounter parameter which relates prey density to attack rate, t, the handling time (where 1/t gives the maximum consumption rate), and m, the shape parameter (values of m>>>1 indicate that switching occurs). 95% Bayesian credible intervals are shown in brackets. Subscripts indicate the prey species for which each parameter was estimated.
