[This species is the " Tingasu " of Azara, and is very 

 common in all the forests and woods, even in the vicinity of 

 Asuncion. It is a quiet, shy bird, slow in its movements, 

 and with a soft flight. Its long tail does not seem to in- 

 commode it in the slightest degree. The favourite perch is 

 close up against the trunk of a tree, its chestnut colour 

 assimilating well with the dark bark. I find it the most 

 parasite-infested of all the " monte " birds, and it seems 

 strange how it can tolerate the hundreds of creeping things 

 which make their appearance about the head and neck 

 after death. Without being absolutely sure, I think that 

 its nest is composed of strips of the thin inner bark of 

 trees and that two eggs are laid of a dull creamy-white 

 colour. — W. F.]
