Southern rockhopper penguin feeding, and foraging but these penguins are able to survive and be shaped due to their variation, ability to adapt over time, and plasticity. As the climate changes, prey and predators have to adapt to survive. This poses a problem for southern rockhopper penguins. Depending on how Crustaceans and other prey adapt to survive, penguins will have to adapt or disperse as well. "E. chrysocome's" foraging behavior is largely dependent and shaped by the environment, including factors like weather and food availability. As temperatures around the world increase then something will have to change once more in order for the
Bird vocalization and prevent an energetically costly fight . In birds with song repertoires, individuals may share the same song type and use these song types for more complex communication. Some birds will respond to a shared song type with a song-type match (i.e. with the same song type). This may be an aggressive signal, however results are mixed. Birds may also interact using repertoire-matches, wherein a bird responds with a song type that is in its rival's repertoire but is not the song that it is currently singing. This may be a less aggressive act than song-type matching. Communication through bird
