This is a little quaker parrot singing something called The Quaker Song. I particularly love the part when he says “yay!” after finishing the song.
Lyrics to the I’m a Little Quaker song:
Sing a song? Ready?
I’m a little Quaker, green and stout
open up the cage and let me out
better pick me up or else I’ll squawk
rub my tummy and then I’ll talk
Yay!! Ha ha ha!
