Theristicus
Genus of birds
From Wikipedia, the free encyclopedia
Theristicus is a genus of birds in the family Threskiornithidae. They are found in open, grassy habitats in South America. All have a long, decurved dark bill, relatively short reddish legs that do not extend beyond the tail in flight (unlike e.g. Eudocimus and Plegadis), and at least the back is grey.

Taxonomy
