A bird usually seen flying in the skies over China and Ireland has found itself in a spot of trouble. You could even say it's in more excrement than a ... Werribee duck.

A lone male tufted duck, named after its luscious plumage, has somehow ended up in the west Melbourne suburb's sewerage farm, far away from any of its mates.

Birdwatchers have swooped on the west Melbourne suburb, which they say is rivalled only by Kakadu for the sport in Australia, to catch a glimpse of the bird never before seen in this country.
