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 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.
