Scientific background

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.Predatory Bird Monitoring Scheme logo

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.
