title: Field estimates of the strength of interference between oystercatchers haematopus ostralegus.
abstract: The rate at which oystercatchers ate mussels was higher when few oystercatchers were present. The calculated strength of this interference (m) was immensely higher than is compatible with those models which assume interference is coused solely by the time predators waste when they encounter each other.
