Buff-necked Ibis ( Theristicus caudatus )

Unmistakably identifiable for being the only Brazilian member of the family to present the white color in its plumage.
Belonging to the same family of the legendary Egyptian Ibis, this is certainly an amazing species. Unlike other members of the family it is not associated to water, living in open grasslands and crops where its large silhouette makes it impossible not to be noticed, especially when they gather in groups.
It uses its large curved beak to catch invertebrates burried in the soil and may also prey on small vertebrates.
Its song is very loud and acute, reminding that of the Seriema ( Cariama cristata ). Couples sing in duets bouncing their heads upwards as they sing.
The large nest is built on tall trees, made of thick sticks. The couple takes turns in sitting the eggs - usually 5 - and feeding the nestlings.
