[This species is common throughout Central Paraguay 

 wherever there are large forests. I do not think there 

 is anything peculiar about it which does not apply to 

 many others of the same family. I have noticed that its 

 favourite hunting-ground is along the banks of the forest 

 streams, but that is the favourite place of other birds which 

 catch flies on the wing. The nest is a wonderful purse- 

 shaped affair some seven inches in length, the entrance 

 leading from below upwards. Suspended as it is from 

 the extreme tip of a slender branch and overhanging a 

 stream it is safe from everything but men, and possibly for 

 this reason the species is so common. All the birds which 

 build in the forks of trees or along the larger branches must 

 pay a heavy toll annually to the numerous snakes, opossums, 

 &c. which inhabit the woods. — W. F.~\

Allied to R. sulphurescens, but differs in being olive-grey 

 above instead of green ; the head somewhat darker and 

 inclining to lead-colour ; tail-feathers pale brown, edged with 

 whitish; quills also pale brown, margined with olive-grey. 

 The two bars on the wings, formed by the margins of the 

 median and greater coverts, are white instead of yellow ;
