Does your long distance relationship have you pining for your partner? Well, at least you aren’t a southern rockhopper penguin (Eudyptes chrysocome). These marine birds mate for life, but don’t spend much time together other than during the mating season, which is only 20-30 days long. Talk about difficult travel logistics: GPS trackers show that penguins have overlapping wintering habitats, but because males and females show up to a nesting site at different times, it may be more work to find each other after the mating season, rather than just meeting up again the next year.
