White-shouldered ibis (Pseudibis davisoni)

The white-shouldered ibis (Pseudibis davisoni) is a large species of bird in the family Threskiornithidae.
The bird is native to small regions of Southeast Asia, and is one of the most threatened bird species on this part of the continent.
This species once extended throughout Southeast Asia from Myanmar to Thailand, Malaysia, Cambodia, Laos, Vietnam and north into Yuman in China.
The bird re-appeared in Dong Thap Muoi (Mekong Delta, southern Vietnam) in 2019 after decades of absence.

Pelecaniformes translates to "pelican-shaped" or "pelican-formed," derived from the New Latin Pelecanus (pelican) + -iformes (having the form of). The term originates from the Ancient Greek pelekan (πελεκάν), which is linked to pelekys (πέλεκυς), meaning "axe," likely referencing the large, axe-like bill of the bird.

Threskiornithidae, the scientific family name for ibises and spoonbills, originates from Ancient Greek and New Latin, meaning "religious bird" or "worshipper bird". It is derived from thrēskeia (Greek for "religion" or "worship") and ornis (Greek for "bird"), likely referring to the sacred status of the ibis in ancient Egypt.

Pseudibis is a scientific genus name for a group of Southeast Asian ibises, derived from a combination of Greek and Latin meaning "false ibis". The prefix Pseudo- originates from Greek pseudos, meaning "false" or "lying," and ibis comes from the Latin/Greek term for the bird.
