Blibbering Humdingers: Buzzing or Humming?
Blibbering humdingers…the finest natural instrument! You, however, will not control this music! The blibbering humdingers will! Blibbering humdingers are small, about the size of a galleon. They have tiny wings, the size of a Knut, one on either side of their body. They have a pointy, tiny beak which makes a humming, or buzzing sound to different tunes they have heard in their lifetime. So basically, if you start singing a Weird Sisters song in front of a blibbering humdinger, they will always be able to play that song by humming/buzzing whenever they wish.
Blibbering humdingers are rather hard to spot. They are so small, that you may not see them flying around. They usually come out between the hours of 5:00am and 3:00pm. Then they go away and sleep in hollowed out trees. Blibbering humdingers have families of about five. One mother, one father, and three children, typically. When baby blibbering humdingers get to be one year old, they leave their house and go find families of their own.
Many people have a debate over whether blibbering humdingers hum, or buzz. Some say, 'Of course they hum! That's why they're called blibbering humdingers!' Others beg to differ. 'It's not really a humming…it's more of a buzzing…it's deeper than humming, I think.' I have, however, found out which humdingers do. They hum. End of story. I asked Newt Scamander himself whether they hum or buzz, and he has informed me that they do, in fact, hum.
