Uncommon. Has a sweet dissyllabic cry, heard occa- 

 sionally at night in the forest. The Tobas believe that 

 possession of one of these birds^ or even of a piece of one of 

 them^ will bring them good fortune.

Abundant, in very large flocks, about the neighbourhood 

 of Fortin Page. Frequently associates with flocks of Bolbo- 

 rhynchus monachus. One of the favourite foods of these 

 species consists of the berries of the parasitic Loranthaceae, 

 which are so common upon some of the trees. 



[This well-known Paraguayan species (the Nendai of 

 Azara) may now be added to the Argentine list. — P. L. S.]
