Theristicus is a genus of birds in the Threskiornithidae family. They are found in open, grassy habitats in South America. All have long, decurved dark bill, relatively short reddish legs that do not extend beyond the tail in flight (as opposed to, for example, Eudocimus and Plegadis), and at least the back is gray.

Taxonomy

Earlier, T. caudatus included T. melanopis as a subspecies, but today all major authorities accept the separation. In addition, it has recently been suggested that the taxon branickii considered a variety, but currently most authorities support it as a subspecies T. melanopis.
