Brown Teal - photographer: Barbara HughesThe brown teal is a warm brown with a dark brown mottled breast
, brown eyes with a narrow white eye-ring. The bill is blue-black. The breeding male has a glossy green sheen on his head, a narrow white collar and a white flank patch.

The brown teal is one of the world's rarest ducks. It was once common but declined in numbers due to predation (by cats, dogs and mustelids) as well as a loss of habitat. It was also hunted until 1921, since when it has been protected under law.

The brown teal calls differ between the sexes. The males give soft, high pitched wheezy whistles and popping calls, the females give low quacks and growls. 

Brown Teal - photographer: Val SmythemanBrown teal are strongly territorial during the breeding season. The nest is a bowl of grass under tussock or fern. The male guards the territory while the female incubates and subsequently raises the brood.

Brown teal eat mainly aquatic or marine invertebrates but on Tiritiri Matangi they have been observed eating vegetation. They often feed at night, and visitors on night walks often come across them on the Island's tracks.

Brown teal were released on Tiri in 1987 and again in 1989 and 2002. The birds released in 2002 were monitored by a research student, and unfortunately four of them were predated within a month of release, probably by harriers. They have always struggled to maintain their numbers on the Island. Although they breed regularly, chicks have a high mortality rate due to the presence of natural predators (not just harriers, but also eels, pūkeko and black backed gulls). Some birds almost certainly leave the Island of their own accord; males, especially, may migrate to nearby estuaries for the winter intending to return for the next breeding season. While away from the Island they are vulnerable to introduced as well as native predators. Some are suspected to have died of botulism.
