Coxen’s Fig-parrot, C. coxeni, was recently split from Double-eyed Fig-parrot, C. diophthalma and listed as Critically Endangered under criterion C2a(i) on the basis that it likely has a very small population, and there is a chance that it may be declining as a result of habitat degradation even though declines may have been largely historical (see BirdLife International 2017). It occurs in remnant small patches of rainforest in a small area of coastal eastern Australia in Queensland and New South Wales (Garnett et al. 2011). Much of its habitat was cleared at the turn of the 20th Century (Coxen’s Fig-Parrot Recovery Team 2001), and what remains could be impacted by the spread of invasive weeds (Garnett et al. 2011).
The species is rarely recorded, but it does continue to be reported (I. Gynther pers. comm. per G. Dutson in litt. 2016). Four subpopulations are thought to remain, provisionally estimated at no more than 50 individuals in each or potentially a total of 100 breeding individuals, but the exact subpopulation structure remains uncertain (Garnett and Crowley 2000, Coxen’s Fig-Parrot Recovery Team 2001, Garnett et al. 2011). This is in line with the data BirdLife already use for the assessment of Coxen’s Fig-parrot. However, Garnett et al. (2011) suggest that the species should not be considered as declining and instead could be considered stable, because given the similar rate of reported sightings of this species, if the species were declining it would have likely gone extinct. This is tentatively supported by the ongoing rate of reports (I. Gynther pers. comm. per G. Dutson in litt. 2016), although essentially the trend is uncertain (G. Dutson in litt. 2016). Therefore, we request any comments or information regarding the population trend for this species, but if it were to be accepted as stable the species would no longer warrant listing as Critically Endangered, and instead would meet the conditions for listing as Endangered under criterion D.
