Food-chain transfer of contaminants is often predictable below the level of birds, but relations between contaminant concentrations in birds and their foods are often weak and variable. Much of this variation probably results from the energetics of foraging in fluctuating, heterogeneous environments, which has not been accounted for in past models of contaminant uptake by birds. Because birds ...
