Habits. This bird according to Schomburgk (liels. Gnian. iii. 

 p. 699) is rare near the coast and inhabits the more open parts 

 of the interior. He first met with it near Wat-ipukari Bay on 

 the Rupununi River. This bird makes itself conspicuous by its 

 loud voice. Its nesting habits are similar to those of P. sulphu- 

 ratns {supra, p. 199.)
