They carry out mutual courtship dosplays in the water. Often these include circling, bowing the head, arching the wings, and performing a kind of shuffling "dance". They may grunt or click. They mate in the water. Males are particularly aggressive and will drive away other species of bird, as well as anything else that happens along.

i have been lucky enough to witness this on several occasions and it is a mesmerising sight,surpassed only by the courtship of gannets!there is much circling in the water and bowing to each other,along with a peculiar sort of shaking motion with the head.there is a reaffirmation of this when they meet up after any kind of separation.they also swim at a similar speed,side by side,which is another method of bonding.

There isn't one, they can't talk!
