This is either a couple or best friends, they swam around together exclusively. I have never seen a duck with a POM POM on the back of it's head. It's either a cheerleader duck or has a Pompadour style "do". It would shake it's head, causing the ball of feathers to swing back and forth.
@meeyauw@mylensonlife Thanks! LOL! Ear muffs! The way he was swinging his head around reminded me of Willow Smith and that song she did swinging her hair around.
