It never amazes me how people will interfere.  Once I was attempting to get a fledgling Meijiro back to it's parents who were teaching it to fly.  This young girl (with her mother watching) was attempting to catch the bird.  I told her to please let it reunite with their parents...did she listen? No.  Did her mother attempt to stop the young girl?  No.  I was able to keep child away and after they left made sure bird's parents were able to link up.  As cute as they are, leave them be.
