The western gerygone (Gerygone fusca) is a small, brownish-grey species of passerine bird, which is found in inland and south-west Australia. It is an arboreal, insectivore of open forest, woodland and dry shrubland. It is not currently threatened with extinction (IUCN: Least Concern).
The western gerygone is a member of the family Acanthizidae (Thornbills and Allies), which has been split from the family Pardalotidae (Pardalotes). It is a sister-species to the mangrove gerygone (Gerygone levigaster). The close relationship of this phylogenetic pair is suggested by analyses of both morphological characteristics and genetic loci. Populations of a common ancestor of the two species are thought to have diverged after becoming fragmented by severe aridity during the Pleistocene. These two species are now in secondary contact in the Carpentarian Basin, but occupy very different habitats and do not interbreed.
The common name western gerygone and scientific name Gerygone fusca are recognized by the taxonomies of the International Ornithological Congress, Clement's Checklist, the Handbook of the Birds of the World and Christidis and Boles. Wikipedia →

Rare
Under 5% of wildlife watchers report a Western Gerygone sighting in Brisbane on a given day, based on 68 verified sightings from GBIF citizen-science data. It is the 184th most-seen of the 237 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Western Gerygone in Brisbane on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Western Gerygone sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 cities where we can rate Western Gerygone sightings, Brisbane ranks 2nd at under 5%. The best odds are in Perth (Australia, about 30%).
GBIF citizen-science records
It is estimated from how often the Western Gerygone is recorded against all the birds logged in Brisbane (68 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.
