This young lion is a member of the Masai Mara Ridge Pride.
Of course I couldn't possible know what was going through his mind but, with that intense stare, I wouldn't be surprised if he was eyeing up some poor unsuspecting wildebeest.
PS: I did, at first, have this down as a female but I'm now pretty convinced it's a male; probably around 3 or 4 years old.
