Most birds made foraging trips to the continental shelf break (1000m isobath ... ) approximately 110 km distant at its closest point. Birds feeding chicks also made journeys of 1-2 days ranging ... where the birds were foraging. There is potential therefore for overlap between the foraging range ...

It was found that 89 % of birds could be correctly sexed ... . The sex of juvenile birds (identified by their white chins) cannot be determined by this method ... of variation. Further, it should be applied only to breeding birds. The probability of correctly identifying ...
