Comment on population trends of southern rockhopper penguins (**Eudyptes chrysocome chrysocome**) on Isla Pingüino, Santa Cruz, Argentina
Abstract: Gandini et al. (2016) recently published a paper showing an exponential population increase of southern rockhopper penguins (Eudyptes chrysocome chrysocome; hereafter: SRP) on Isla Pingüino, Santa Cruz, Argentina (hereafter: IP). Alongside population counts, reproductive success was measur...
