8.5 week Parrotlet , singing to himself. 

He likes to sing, when he's relaxing somewhere. Whether it's in the cage or not. I have heard him before, and heard him wolf whistle, in between his little chirps. I wanted to record him, but did not want to distract him. If he saw me for too long, he would just beg to come out and play lol. So I put my cell phone face down, above him,on top the cage.
