Protecting the Forty-spotted Pardalote


This project is focusing on improving knowledge of Forty-spotted Pardalote’s life history, population size and its conservation needs.



Endemic to eastern Tasmania, the endangered Forty-spotted Pardalote (Pardalotus quadraginatus) survives in small, isolated mainland populations in the island’s south east, as well as on offshore islands including Flinders, Maria and Bruny. It is under threat from the loss of its habitat (principally white gum – a critical feeding resource), its small population size, and the death of nestlings due to the larvae of an endemic parasitic fly that can kill up to 81% of chicks in infested areas.

  • Research into whether dispensers containing insecticide-treated feathers can help combat the fly larvae in their nests on north Bruny Island.
  • Examining the environmental characteristics of artificial nest boxes that makes them more likely to be used by Forty-spotted Pardalotes.
  • Using the results of this research to determine interventions that could increase Forty-spotted Pardalote populations across their range.
  • Examining the genetics of the population and assessing the potential effectiveness of various management interventions.


  • Trials of feather dispensers have been undertaken and will be completed during the 2022-23 year.
  • Genetics data has been collected and processed and this work is currently being prepared for publication.
  • Surveys on nest box data from islands around Tasmania were collated and data analysis is underway.
