The long neck and upright posture gives the duck the appearance of a small goose. The male has a brown head with substantial drooping crest, chestnut-speckled grey breast, grey body and black rump, tail and under tail coverts.
The female has distinctive stripes above and below the eye on a brown head.
I haven’t followed this up, but every tiny duckling I’ve ever seen, (and I’ve seen and/or photographed many), seems to have the stripe up and below the eye. So I’m not sure whether all ducklings have this and the males head feathers change to all-brown as they grow OR, I’ve only ever seen female ducklings 🙂
I WAS WALKING TO NEWELLS PADDOCK NATURE RESERVE WHEN I SPOTTED THESE TWO DUCKS SITTING ON A WOODEN JETTY ON THE MARIBYRNONG RIVER
