Are these Drones?

The stingless bees have been swarming near the hive for 3 days and I don't know why.  Could it be a mating flight?  Are my bees absconding?  Are some of the bees splitting and making a new colony somewhere else? I have read an article saying that stingless bee drones have a tendency to swarm especially on a favorable weather.  It was a beautiful weather during the swarm and rainy season is just starting.  I caught some bees from the swarm for some photo shoot.  I hope someone can help identify if these are drones.  Here are the pics:

Here is a video clip of one of the bees caught:

I hope anyone can help.  Please send me a message or comment.  Thanks.
