A Note On Pesticide Residues In Great Shearwaters

R.G. Gibbs


The Great Shearwater (Puffinus gravis) breeds only on the Tristan da Cunha group in the S. Atlantic. No live bird of this species has been seen off Trinidad, but a number of dead or dying birds have been washed up on the E. coast in 1971-2. A fuller account of these records will be given in a forthcoming paper by C.T. Collins, and this note deals only with one aspect - possible contamination of these birds with pesticide residues.
