Population justification: The population size of this species has not previously been estimated specifically. The density of Wallacean congeners has consistently been recorded at c.4-4.5 individuals/km2 (see Jones et al. [1995] and Marsden [1998]) and based on qualitative descriptions of abundance in Eaton et al. (2021), this density is deemed appropriate for T. funebris. Within the species' range, c.13,000 km2 of forest remained in 2021 (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). Assuming an occupancy rate of 30-60% to reflect the species' description as scarce (Coates and Bishop 1997, Eaton et al. 2021), although also noting it is elusive, the population is inferred to number c.15,000-35,000 individuals, equating to c.10,000-25,000 mature individuals.

Trend justification: Over the past three generations, 6.5-10.0% of forest within this species' range has been lost (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). Losses are also projected into the future and may accelerate (to a rate equivalent to c.10-15% over three generations) between 2020 and 2053 (Voigt et al. 2021). As a forest dependent species (that apparently shuns edge; Eaton et al. [2021]) the rate of forest loss is thought to be broadly equivalent (or perhaps slightly less than) population losses, thus the past rate of population reduction is suspected to be 5-15% over three generations, while the future rate of reduction is suspected to be 10-19% over three generations.
