The forty-spotted pardalote (Pardalotus quadragintus) is one of Australia's rarest birds and by far the rarest pardalote, being confined to a few colonies in the south-east corner of Tasmania, mainly on Maria Island and Bruny Island.
A small, energetic passerine about 9 to 10 cm (3.5 to 4 in) long, the forty-spot is similar to the much commoner spotted pardalote (Pardalotus punctatus), but has a dull greenish-brown back and head, compared to the more colourful plumage of the latter, with which it shares its range, and there is no brow line. The rump is olive, the under-tail dull yellow. The chest is white with light yellow tints. The wings are black with white tips, appearing as many (closer to 60 than 40) discrete dots when the wings are folded. There is no seasonal variation in plumage; juveniles are slightly less colourful than the adults.
The forty-spotted pardalote is as of September 2021 found reliably only in a few isolated colonies on south-eastern Tasmania, most notably on Maria Island and Bruny Island. These two islands contain 99% of the species' population; there are a few colonies scattered across mainland Tasmania, and... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Forty-spotted Pardalote is recorded against all the birds logged in Maria Island National Park (96 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.
