Geographic Range



Population Information

The newly split species has almost completely disappeared from the wild within the past few decades, a decline that has gone largely unnoticed due to the species previously being included with the widespread G. contra. Wild populations are thought to have gone extinct on Sumatra sometime between 1990 and 2000, had been reduced by 2010 to a tiny remnant in a remote area of central Java (known from trapped birds) and a small population on Bali that may be derived from escapes (Eaton et al. 2015).


Large numbers, apparently of this taxon, are being bred in commercial bird farms in central Java to supply the trade. However, imports of other taxa into Java and apparent mixing of these in captivity seem likely to have reduced the likelihood there being a source of G. jalla stock for conservation breeding (Collar et al. 2012, Eaton et al. 2015)
