The Sunda teal (Anas gibberifrons), also known as the Bebek cokelat or Itik benjut, is a dabbling duck found in open wetlands in Indonesia and Timor-Leste. The species formerly included the Andaman teal Anas albogularis and the grey teal, Anas gracilis as subspecies, but is currently considered monotypic.
A molecular phylogentic study published in 2009 that compared mitochondrial DNA sequences from ducks, geese and swans in the family Anatidae found that the Sunda teal is a sister species of the chestnut teal (Anas castanea) native to Australia.
This is a mottled brown duck with white and green flashes on its wings. The male and female Sunda teal share the same colouration, in contrast to the related chestnut teal, whose male and female are strikingly different. The nominate Sunda teal has almost identical colouration to the female chestnut teal and can only be distinguished by its lighter coloured neck, paler face and especially the bulging forehead. The Andaman teal has a variable amount of white on the forehead and around the eyes. The Rennell Island teal looked like a smaller version of the nominate subspecies, with a stubbier bill. Juveniles are paler than adults, especially on the head.
The Sunda teal nests near its favoured freshwater lakes and marshes, usually on the ground, but also in tree holes or rabbit burrows. This is a vocal duck, especially at night. The male gives a soft peep, and the female has a loud quack. Wikipedia →

Rare
Under 5% of wildlife watchers report a Sunda Teal sighting in Way Kambas National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 191st most-seen of the 205 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Sunda Teal in Way Kambas National Park on a given day, against under 5% in March–July and September–October, the lowest months. That is one of Way Kambas National Park's driest months, with about 90 mm of rain against 370 mm in March. November to February have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Sunda Teal sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 parks where we can rate Sunda Teal sightings, Way Kambas National Park ranks 3rd at under 5%. The best odds are in Bali Barat National Park (Indonesia, about 10%) and Komodo National Park (Indonesia, under 5%).
Same family: Anatidae
The closest relatives of the Sunda Teal that you can see in Way Kambas National Park (family Anatidae, Ducks, Geese, and Swans) are Lesser Whistling-Duck (about 10%) and White-winged Duck (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sunda Teal is recorded against all the birds logged in Way Kambas National Park (8 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
