  • Slow breeding cycle

White-Shouldered Ibis, a wading bird from the Threskiornithidae family, was first given a name and subsequently described by William Ruxton Davison and David Hume, respectively.

Its natural habitat can be found mostly in rice fields, shrubby grasslands, and dry forests in Southeast Asian countries, with most of its population inhabiting Cambodia. This terrestrial bird species forage for food in muddy places instead of clear waters. During adulthood, it can grow between 60 and 80 inches in height. Males are larger than females. It has a slate-black head, dull reddish legs and brownish-black plumage with glossy blue-black wings and tail. Its bill is a yellowish grey colour and has a curved shape that is advantageous in seeking its prey in hard cracked ground.

The main threat to its existence is intentional hunting by humans. Due to large forest fires throughout the years that also affected its native habitat as well as infrastructure development in the surrounding areas, it became more vulnerable to getting caught and being killed if not for the slow breeding cycle due to lack of food or suitable nest options.
