Well, its not my field so I don't even know which key science groups to look at on this one - animal behaviorists, biologists...I'm not sure. And then I have no idea the state of research.
But I am certain that it won't be Women's studies.
Unless one can talk to the animals, one can't be sure of the reason they're doing the strange things they do nor is what the animals do necessarily of net benefit to human beings.
