And male lions will always try and give their best to protect the lion cubs from danger. A father lion will always try to defend his cubs, while in the other case an intruder male lion will always hate the cubs of another pride and will be always ready to kill those cubs if the cubs are not well secured. Also, intruder male lions after taking over a new pride are seen to hate the cubs of that pride as they cannot sit around with patience without having sex with the lioness.
And so, it is often seen in the wilderness that the new dominant and intruder male will always opt to kill the cubs that are not theirs after taking over the pride and start a new generation that is theirs genetically.
Females are clever and they act wisely when they see that a new intruder male has taken over the pride. So, they opt to better mate with the new males, and bring their cubs out later making the male think that these are his cubs. This saves the cubs from getting killed. If you see this from the genetic point of view then you will learn that the new male almost always kills the new pride cubs after taking over the pride, if the cubs are not well secured.
This ensures the continuation of the lineage with proper chances of surviving in the long-run. Yes, the lioness does grieve when her cubs are killed by another lion. They are known to show various mourns and make various sounds just in order to show their grieve when the cubs get killed. In the wild, it has also been seen that some lionesses have been known to eat their dead offspring as a way to help cope up with the loss.
It has also been seen that lionesses try a lot to save their cubs from being killed by a new male who has taken over the pride. In the wild, it has also been seen that other big cats like leopards, cheetah, other animals like hyenas, wild dogs, etc. Such cause can also make the lioness grieve. Lionesses have evolved in such a way and they are used to such cases. One possibility, Mr Funston said, is that Zuri - who is described by the zoo as "an attentive and protective mother" - became fearful of Nyack, which led to the fight.
Zuri's natural instincts could have taken over at that point, he explained, and so she ended up killing him. Bruce Patterson, a researcher at the Field Museum in Chicago, said he knows cases of wild lionesses that have attacked - and injured - male lions who upset them. Mr Funston, who has studied lions for 25 years, acknowledges this is "an unusual" and "rare" incident - but that does not mean it is is necessarily strange.
But this is a highly socially complex species. Lioness kills father of her cubs at zoo. Lions eat suspected big cat poacher. What killed 11 Indian lions? Image source, Reuters. Lioness Zuri had lived with Nyack for eight years and the zoo said the two had never shown aggression before.
