St. James's Park: How To Choose?

Harder to call in large...

I couldn't work out how to choose my blip...
Cuteness contest?
Dancing contest?
Prettiest plumage?

I opted out: these scrapping coots (the onlookers joined in moments later) were the most dramatic moment, and I was too biased to judge the contests...

Cuteness contestants: 
Ruddy shelduck, Smew, Hooded merganser, Ross's geese
Dance contestants: 
Shelduck shake, Smew, Synchronised whistling ducks, Black swan, Littlest cow goose, Largest cow goose
Plumage pageant: 
Ruddy shelduck, Shelduck, Smew, Hooded merganser, Chiloe wigeon, Heron, Black swans, Red-crested pochard
