[This species is resident and not uncommon in the district. 
It is a forest-loving bird and is very rarely met with in 
the open except during planting-time, when the newly turned 
earth evidently attracts the bird in search of iusects,—

[This species is common and resident in Paraguay, where 
it is the special aversion of the agriculturist, owing to the 
impudence with which it digs up the maize as soon as the 
leaves shew above the ground. In this way a flock will, in 
a day or so, utterly destroy a large field of corn, unless 
it is very carefully watched. The birds are so used to being 
frightened away that they go only to the edge of the forest. 
The Paraguayan is too poor to be able to shoot, and well the 
birds know that no harm can come to them for trespassing, 
while at times the damage done is considerable; between 
locusts and Chopis the poor planter has a bad time of it. 
Cyanocorax cceruleus is as impudent and daring as the Chopi, 
and both are so common that planting is not one of the 
easiest things imaginable.— W. F.]
