The brown antechinus (Antechinus stuartii), also known as Stuart's antechinus and Macleay's marsupial mouse, is a species of small carnivorous marsupial of the family Dasyuridae. The males die after their first breeding season, and the species holds the world record for being the world's smallest semelparous mammal.
Antechinus stuartii is mostly light brown above, including the upper surfaces of its feet, and a lighter brown below and on its tail. Its body length is 93–130 mm (3.7–5.1 in) and its tail 92–120 mm (3.6–4.7 in), and it weighs 16–44 g (0.56–1.55 oz). Unlike in other members of Antechinus, no pale-coloured eye ring occurs. Antechinus agilis is similar in appearance and difficult to distinguish except by its distribution.
The brown antechinus was only the third in its genus to be described and as such, until recently, has included species such as the agile antechinus (Antechinus agilis), the subtropical antechinus (Antechinus subtropicus), and the tropical antechinus (Antechinus adustus). It has also been included itself with the yellow-footed antechinus as the subspecies A. flavipes burrelli. It was described in 1841 by the entomologist William... Wikipedia →

No species of the same family or order lives in Sydney, so these are its closest relatives here: other mammals.
Rare
Under 5% of wildlife watchers report a Brown Antechinus sighting in Sydney on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 16th 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.
June to August
In those months about 10% of wildlife watchers report a Brown Antechinus in Sydney on a given day, against under 5% in September to May, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Brown Antechinus sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Sydney, in our data
Sydney is the only city on Wallace's Line with enough records to rate Brown Antechinus sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Brown Antechinus is recorded against all the mammals logged in Sydney (19 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.
