1. Fisheries risks to the population viability of black petrel (Procellaria parkinsoni)

   Abstract:  Data on the main population of black petrel (Procellaria parkinsoni), which breeds on ... Great Barrier Island, were analysed. Three types of data were available. The most useful was abundance ... population. The mean age of first breeding for black petrel is estimated to be 6.7 y. Before this, new adults ... spend an average of 1.2 y in the colony as pre-breeders, with only 3% skipping the pre-breeder phase. Of ...
