Pepper, a Magellanic Penguin, did not find new love this breeding season.
Last season, he was dumped by his long-term, same-sex partner Harry -- for a girl penguin Linda.
This year, zookeepers see signs of tension between the three -- they're also worried that Pepper has been keeping to himself instead of making friends like other singles.
Pepper and Harry and been together since adolescence and raised an abandoned egg together. But now, Harry and Linda are incubating an egg.
