About the Javan Rusa
The Javan rusa or Sunda sambar (Rusa timorensis) is a large deer species native to Indonesia and Timor-Leste. Introduced populations exist in a wide variety of locations in the Southern Hemisphere. Rusa is the Malay word for "deer" in general as well as lending the name to its own genus.
The Javan rusa is dark blackish brown and has a gray forehead. Its back is almost black, the underparts and inner thighs are yellowish brown. The abdomen is lighter brown, and the tail tuft is dark blackish brown. The hair is coarse and longer on the chest than on the remaining body. Its ears are wide and a little shorter than the head. The antlers are medium long and rather wide, the upper branch points forward. Fawns are born without spots. Males are bigger than females; head-to-body length varies... Wikipedia →

What are the chances of seeing a Javan Rusa in Sydney?
Rare
Under 5% of wildlife watchers report a Javan Rusa sighting in Sydney on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 22 mammals 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.
When is the best time to see a Javan Rusa in Sydney?
November
In that month about 10% of wildlife watchers report a Javan Rusa in Sydney on a given day, against under 5% in December to October, the lowest months.
What time of day is best to see a Javan Rusa?
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Javan Rusa sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Where else can you see a Javan Rusa?
Only Sydney, in our data
Sydney is the only city on Wallace's Line with enough records to rate Javan Rusa sightings: under 5% of wildlife watchers there report one on a given day.
Where does the Javan Rusa sighting chance come from?
GBIF citizen-science records
It is estimated from how often the Javan Rusa is recorded against all the mammals logged in Sydney (17 verified sightings), 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.
