Gould's wattled bat (Chalinolobus gouldii) is a species of Australian wattled bat named after the English naturalist John Gould. C. gouldii is the largest of the genus Chalinolobus, a group distinguished by fleshy lobes located at the corners of its mouth. For individuals throughout their range, the average length (head and body) is 70 ± 5 mm and average mass is 14 ± 4 g. The fur on the back is dark brown, becoming black on the head and shoulders.
C. gouldii is known throughout mainland Australia (excluding northern Cape York Peninsula and Nullarbor Plain) as well as Tasmania, New Caledonia, and Norfolk Island. C. gouldii is found in a variety of habitats. In wooded areas, they are mostly arboreal, though they have also been found in the stumps and hollow limbs of trees or in bird nests. They may also inhabit urban settings, such as the ceilings and basements of buildings. While some individuals (usually males) may roost alone, colonies often hold about 30 bats. Colonies of up to 200 individuals are also known.
C. gouldii is active year-round across most of its range, but enters hibernation in cooler climates. This torpor... Wikipedia →

Rare
Under 5% of wildlife watchers report a Gould's Wattled Bat sighting in Brisbane on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 22nd 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.
December
In that month about 10% of wildlife watchers report a Gould's Wattled Bat in Brisbane on a given day, against under 5% in January to November, the lowest months. That is one of Brisbane's wettest months, with about 130 mm of rain against 40 mm in July.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Gould's Wattled Bat sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
3rd of 3
Of the 3 cities where we can rate Gould's Wattled Bat sightings, Brisbane ranks 3rd at under 5%. The best odds are in Perth (Australia, about 10%) and Melbourne (Australia, under 5%).
Same order: Chiroptera
The closest relatives of the Gould's Wattled Bat that you can see in Brisbane (order Chiroptera, Bats) are Black Flying-fox (about 20%) and Grey-headed Flying-fox (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gould's Wattled Bat is recorded against all the mammals logged in Brisbane (6 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.
