Wizards in India

Are there wizards in India?  I mean of the Wizard of Oz variety. 
Something that used to scare the living daylights out of me as a kid watching that Judy Garland film was the sight of those flying monkeys.  I could cope with the wicked, green witch, but those monkeys - Google-map the toilets!
After visiting one of the schools north-west of Bangalore, our group was taken to a Hindu Temple high on a hill with breathtaking views.  Driving up the winding road, we passed a few monkeys and were advised to keep the windows closed.  When we arrived at the temple, there were lots of oohs and aahs upon seeing the cute baby macaques clinging to their mothers.  All gentle enough.  As soon as we left our vehicle, however, we were immediately surrounded by about a hundred that appeared from different parts of the ancient building.  They walked beside us, behind us, in front, and overhead on some of the stone beams outside the temple entrance.  They came running, looking for food, cameras, phones, water bottles, anything they might get their hands on.  One grabbed a colleague's bag and wouldn't let go.  It bared its teeth and screeched menacingly.  Others jumped down from the overhead structures.  I was reminded of another film - Hitchcock's The Birds.
Fortunately, we were rescued by some workmen doing some repairs to the building.  They shook their sticks which was enough for the marauders.  But before we entered the temple, I'd noticed something odd.  When the monkeys jumped down from their higher perches, there was one that seemed to glide through the air a bit more slowly than the others.  Something protruded from its back.  Some deformation I didn't get close enough to examine. 
So, with great humility and respect, we entered the darkness of the temple, appreciated the solemnity of the place and began to leave wondering if we would have to face the same gauntlet run once we were outside.  But the macaques had all gone.  All but one.  It sat on a low wall and looked me straight in the eye.  I think it could tell.  It knew what scared the living daylights out of me.
