QUESTION: Do different species of penguins fight with each other? Fourth graders in Greeley, CO, USA Ms. Heisler's Class ANSWER from David Lott, Researcher, Palmer Station, Antarctica Fri, 14 Feb 1997 16:37:54 -0500 Dear Fourth Graders and Ms. Heisler, There were a couple of different species at the island where I was working. The different species would peck at each other, but not more than they would peck with those of the same species. I think that a penguin might be defensive of anything that comes too close to its nest despite what species it is. Thanks for your question! David Lott
