In this subgenus, on the contrary, the base of the beak is furnished 

 with feathers which open at top, and form a large panache resem- 

 bling a parasol. 



One species only is knownj it is as large as a Jay, and blackj 

 the feathers at the bottom of the breast form a sort of pendent

The Crown-Birds have the depressed beak of the Flycatchers, but 

 it is somewhat shorter in proportion, tolerably broad and slightly 

 arcuated. 



Those in which it is the most pointed and strong, have still a de- 

 cidedly insectivorous regimen: they are called Piauhau from their 

 note the Querula, Vieill. They inhabit America, where they pur- 

 sue Insects, in flocks. (2) 



The Common Crown-Birds, 



Whose beak is rather weaker, besides insects, feed on berries and 

 tender fruits. They inhabit the low grounds of America, the males 

 being remarkable, at the nuptial season, for the brilliancy of their

The Piauhau d gorge aurora {Coracias scutata, Lath, or Coracina scutata, T.), Col.
