Population justification: There were an estimated c.50 individuals in the West Bali National Park in 2008 (Dijkman in litt. 2008). On Nusa Penida, the population was recorded as 65 adults and 62 juveniles in 2009 (C. Kenwrick in litt. 2009). However, given that the population estimate should only comprise of mature individuals, and the IUCN stipulates re-introduced individuals must have produced viable offspring before they are counted as mature individuals, the current population of 115 individuals should be considered a maximum, and as such the population is precautionarily assumed to be fewer than 50 individuals and mature individuals.
Trend justification: The wild population has been maintained only by release of captive birds, so is essentially gradually declining. However, signs from the reintroduced colony on Nusa Penida and West Bali National Park are promising, with both populations breeding and apparently increasing.
