Parrot Cries Like A Baby [VIDEO]

I grew up with a parrot. That parrot could mimic voices and stuff, BUT nothing like this.  This parrot obviously lives with a newborn baby; a crying newborn baby. In fact, the baby cries so much that the bird has it's 'cry' down to the tee.  It's almost eerie. So how does the mom know if it's the baby crying or the bird doing his thing?
