You may remember Diana’s post from last year about the interesting dynamic in the relationship between Jamie and Burrito. As it happens, Missy and Negra have a complicated relationship as well. When it comes to food, Negra is definitely more dominant and Missy will generally let her have whatever she wants, even if it is reluctantly. You might think that this dynamic would affect their friendship, but it doesn’t seem to, at least not in an obvious way. Missy doesn’t appear to hold a grudge against Negra for pulling rank and is just as happy to play with her as with her friend Annie when the opportunity arises.
It is interesting to note that a similar dynamic exists between Annie and Missy but in this case it is Annie that gives up her food at Missy’s request. So, I imagine it’s not just Missy and Negra or Jamie and Burrito that are complicated. Overall chimpanzee social relationships appear to develop much more complexity than a simple dominance hierarchy suggests.
