Which critically endangered bird is the national bird of Cambodia?

The critically endangered bird that is Cambodia’s national bird is the giant ibis.

The giant ibis (Pseudibis gigantea) is the largest living ibis species, a dark gray-brown wading bird with a bare gray head and neck. Cambodia selected it as a national symbol because the species is closely associated with the country’s remaining dry forests and wetlands. Although it once ranged across much of mainland Southeast Asia, it is now concentrated mainly in northern and eastern Cambodia, with only occasional records elsewhere.

Its decline reflects the loss and fragmentation of lowland deciduous forest, hunting, disturbance, and changes to seasonal water sources. The giant ibis is often confused with the white-shouldered ibis, another critically endangered Cambodian bird; both are rare, but they are separate species. Conservation programs protect nesting trees, involve local communities, and reward habitat-friendly farming around important strongholds.
