Chestnut-breasted Shelducks are richly plumed birds. The sexes are different – the female is smaller, has a narrow white ring around the eye and a richer chestnut breast.
I still always think of them as ‘Mountain Ducks’, that’s how I knew them as a child growing up. It’s a misnomer really, as this species is more at home on plains country than elsewhere. After breeding they gather in loose congregations, or sometimes in massive ‘moulting flocks’. At these times they are vulnerable to predation as they endure short periods of flightlessness while completing their moult.
