Factors causing predation of the clam paphies (Mesodesma ventricosa), the well-known ” toheroa,” by black-backed gulls are described. Counts of black-backed gulls made at approximately monthly intervals along a 23 kilometre stretch of beach between January 1970 and January 1971 and in December 1972, together with further observations between 1968 and 1975 show that black-backed gulls are important predators of toheroa.
