The young bird differs from the adult in being pale rufous 

 brown above instead of olive-brown ; the head and sides of 

 the face are cinnamon-rufous, somewhat paler on the latter ; 

 the throat and chest similar in colour washed with yellow, the 

 remainder of the under surface is yellowish; the wing-coverts, 

 inner secondaries, and tail-feathers are broadly margined 

 with rufous instead of buff as in the adult. 



[This species is resident and not uncommon in the wooded 

 districts of Central Paraguay. A lover of the gloomy thickets 

 of the forest, it is never met with in the open parts, but 

 seems to delight in the tangled undergrowth and low- 

 growing trees, undoubtedly finding this a profitable hunting- 

 ground. — W. F.]
