Abstract
The diet of the Antarctic shags was investigated at Paradise Bay, Antarctic Peninsula, by the analysis of 20 pellets collected during the 2015/16 breeding season. Fish were the most frequent and important prey, accompanied by Polychaetes. Amongst fish, only benthic-demersal species were represented in the diet. Harpagifer antarcticus, followed by Notothenia coriiceps, was the most frequent prey and the most important by number and mass. The results are compared with the diet reported for this shag at other localities of the South Shetland Islands and of the Antarctic Peninsula and discussed in terms of geographical significance, breeding output, and population trend.
期刊介绍：
Polar Biology publishes Original Papers, Reviews, and Short Notes and is the focal point for biologists working in polar regions. It is also of interest to scientists working in biology in general, ecology and physiology, as well as in oceanography and climatology related to polar life. Polar Biology presents results of studies in plants, animals, and micro-organisms of marine, limnic and terrestrial habitats in polar and subpolar regions of both hemispheres.
