Mary Midgley writes in her book, Beast and Man (p. 54 in this eBook: https://goo.gl/3NnhtP):
Lorenz gives chilling examples from roe deer and doves, in both of which species stronger members will slowly murder weaker ones if kept in captivity with them[...]
I find this fascinating but I was not successful in finding any more info on this phenomena on the internet.
Can any biologists point me into a good direction? I do not have the work of Konrad Lorenz at hand, and would not know where to exactly look for in them.
Thanks a lot!
