Updated and Extended GLM results for the South Coast penguin colony foraging data

The GLM model to estimate the impact of fishing on penguins at the St Croix and Bird Island colonies is updated given further data. While the additional data result in little change to the results for Bird Island, they suggest a lesser negative impact of fishing around St Croix on penguins than was the case previously. This seems mainly attributable to relatively poor values for penguin response variables at St Croix in 2016 when the neighbourhood of the island was closed to fishery.
