The predatory bird monitoring scheme (PBMS) investigates the impact of chemical pollutants on predatory bird populations. This is achieved through the measurement of contaminants in the tissues of raptors found dead and submitted to the scheme by members of the public.

The predatory bird monitoring scheme (PBMS) is a long-term, national monitoring scheme that quantifies the concentrations of contaminants in the livers and eggs of selected species of predatory and fish-eating birds in Britain.

We monitor the levels of contaminants to determine how and why they vary between species and regions, how they are changing over time, and the effects that they may have on individual birds and on their populations.
