“ At times, more especially just about sunrise, the commu-

din. They utter loud and very harsh cries, something like the 
sound of a gigantic rattle, or of the syllables ‘chacarata, cha- 
carata,’ from which they get their Guarani name, ‘Charata.’ 
All the birds in one part of the forest uniting in this, the effect 
is almost deafening. Other companies of birds answer, and 
on a fine morning in the Chaco, just after sunrise, one hears 
these Charata-choruses resounding in all directions. 
“The Charata is a favourite article of food with the Indians, 
who attract it by imitating the call-note, and shoot it with 
bow and arrow. Amongst the Tobas it is called “ Cochine,” 
in imitation of its call.”
