A historic photograph (1890s) of a once massive African penguin colony on Namibia’s Halifax Island, is a stark contrast to the scene I re-photographed in 2017. The colony probably once numbered more than 100,000 penguins, but today less than 2000 breed there. Historically the demand for guano (bird excrement used for fertilizer) and egg collecting were the principal causes of the decline. Today overfishing of sardines, the penguins’ preferred prey and climate change are preventing these charismatic seabirds from recovering to historical numbers. Unpublished photograph from the July 2018 @ナショナルジオグラフィック magazine feature ‘Lost At Sea’. Photographic field work for this story was supported by a grant from @insidenatgeo
