[This species is the “ Tingasu * 9 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.]
