Prey consumed by the penguins. a shows the species accumulation curves corresponding to the prey consumed by adult and chick gentoo penguins Pygoscelis papua from the colony at Devils Point, Byers Peninsula, Livingston Island, South Shetland Islands during chick guard (December 2016), and b by adult and chick chinstrap penguins Pygoscelis antarcticus breeding at Vapour Col rookery, Deception Island, South Shetland Islands, during chick guard (January 2017). c illustrates the isotopic niches based on δ13C and δ15N. Values were measured in red blood cells of adult and chick gentoo penguins from the colony at Devils Point, and of adult and chick chinstrap penguins Pygoscelis antarcticus breeding at Vapour Col rookery
