in exceptional cases, floating. This nest is placed in some narrow 

 channel or near the side of a lagoon/ and contains from four to 

 six oval buffish-white eggs. The female rises silently when dis- 

 turbed, nor do the parents usually attack an intruder: but wounded 

 birds are dangerous to approach, and make good use of their sharp

 Palmnedea cornuta, the Horned Screamer, found from Guiana, 

 Venezuela, and Amazonia to Ecuador and Eastern Peru, is glossy
