Eight clutches of eggs, which vary from two to four in 
number, collected during the month of October, are usually 
drab-colour with brown spots, more thickly massed at the 
larger end, where they form a zone ; the underlying spots are 
lead-grey. The measurements vary:—axis 1 15 to 1*4 and 
diameter 0*85 to 0 - 95 inch. 
[This species is common and resident. It is one of the 
most impudent of all the birds and the greatest pest to the 
agriculturist; it will at times follow the native Paraguayan 
and dig up the grains of maize as soon as they are planted. 
The easiest way to secure a number of individuals is to 
wound one slightly and make it cry out, then all the other 
birds within a wide area will come to assist their companion, 
almost attacking the hunter in their anger. The nest is not 
to be distinguished from that of C. cceruleus, but the eggs, 
although the same in number and size, are differently marked.
