Worldβs Most Endangered Parrots #7
Once common across several Indonesian islands. Today, one of the worldβs most endangered parrots. ππ¦
The Yellow-crested Cockatoo (Cacatua sulphurea) has suffered a dramatic decline, driven largely by decades of trapping for the bird trade. Between 1981 and 1992 alone, almost 97,000 birds were officially reported as exported - and illegal trade continued beyond the official numbers.
Today, fewer than 2,000 mature birds remain in the wild, scattered across a fraction of their former range.
But there is still hope. Conservation, nest protection and anti-poaching efforts are protecting the remaining wild populations. And an unexpected part of the speciesβ story may lie far outside its native range: established feral populations, including birds in Hong Kong, could potentially preserve genetic diversity valuable for future conservation.
