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 

 1 sad-grey. The measurements vary : — axis 1 15 to 1*4 and 

 diameter 0*85 to 095 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, arc differently marked.
