Crotophaga major
The Greater Ani has not been seen in the Cambyreta area but is occasionally seen in the forests along the river Parana.
It is a large bird of around 40cm. Like the Smooth-billed Ani is has an unusual looking bill with a prominent projection at the top. The colour is striking with blue and green sheen on the predominantly black feathers. The long tail has a bluish sheen and the iris is pale.
The call is a pleasant chatter.
The Argentine name is Ano Grande.
