Anon, must be well read!
Ya it would seem some males are flying solo these days. Then on the other hand, their are a demographic of male, that are not in this selfish way that was spoke of.
"It is also to be noted that male tigers may have large territorial boundaries with numerous female mates inside that territory. In such cases, if the father tiger is inside his territory then he will help raise the cubs of all those females with whom he has mated recently."
"Instances of tiger cubs being spotted alone with the father male tiger raising and caring for them have also been reported in the wild in some of the rare scenarios, like when the mother died when the cubs were still 2 months old."
At least we found a contradicting artical, you know I cherish good scientific debate (even decade long perpetual ones).
