There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.
I think when lions inflict serious injuries to other lions, even in a 2v1 situation, the attacking lions will at least sustain some nasty cuts. We can observe it in fights from the past between other coalitions.
Although the blood and mane may imply a more serious confrontation my bet is that they ran after a quick fight and are fine, otherwise the PCM would be showing some more clear injuries.
But anyway there's no way to know, we'll find out when the Birminghams are sighted again.
