Every year, 40-50 million non-native gamebirds (ring-necked pheasant Phasianus colchius and red-legged partridge Alectoris rufa) are released in the UK, equivalent to around 46000 tonnes of biomass. Fewer than half these birds are shot, with the remaining birds predated, scavenged or surviving to breed or to be predated in subsequent years. This means there is potentially a large food resource available to predators and scavengers; a resource that has increased year-on-year as the numbers released have grown.
