These species are endangered, with only 100 pairs surviving in the world. The giant ibis bird is also known as 'cocos,' 'corocoros,' and 'bandurrias.' These birds resemble herons and also share a few behavioral traits and habitats with them.

They are also similar to storks. The spatulas are the closest relatives of the giant ibis.

Efforts are being done to increase the population of these bird species. The reasons behind the decline of these species are hunting, deforestation, and more. They can be encountered near watering holes of dry forests with a bit of luck.
