White-Shouldered Ibis
Pseudibis davisoni

Conservation Status

IUCN Classification

Critically Endangered (CR)

Estimated Population

Around 1,000 individuals

including roughly 670 mature birds

Key Facts

  • One of the rarest and most threatened birds in Southeast Asia 
  • Cambodia holds the majority of the world population 
  • Usually seen alone, in pairs, or in small groups 
  • Feeds mainly on frogs, insects, small reptiles, and aquatic invertebrates 
  • Prefers seasonal pools, dry forest wetlands, and open dipterocarp forest habitats 
  • Breeds during the dry season when shrinking pools concentrate food sources 

The White-shouldered Ibis is highly sensitive to disturbance and relies on intact forest landscapes with seasonal waterholes for feeding and nesting.

Where to See

The best locations for sightings are in Cambodia’s Northern and Eastern Plains:

  • Tmat Paeuy  Community Protected Area 
  • Kulen Promtep Wildlife Sanctuary 
  • Eastern Plains Landscape (Mondulkiri) 
  • Mekong Flooded Forests between Kratie and Stung Treng 
  • Siem Pang Wildlife Sanctuary 

These habitats are globally important strongholds for the species.


Best Time to Visit

  • Recommended season: December to April 
  • Why: During the dry season, birds gather around shrinking waterholes and seasonal pools, making them easier to observe.


Recommended Length of Stay

  • 1 to 3 days 

A short stay in key habitats is often enough to maximize your chances when guided by experienced local experts.
