HORNED SCREAMER 
(Palamedea cornuta). 
Length: 3 feet. Range: 
South America: Gui- 
anas and Amazon Val¬ 
ley. 
Young horned scream¬ 
ers are reared to defend 
the poultry of natives 
from birds of prey. 
Their sharp-spurred feet 
and wing-tips make them 
formidable warriors. 
The slender “horn” on 
the head of adults is 
usually more than three 
inches long. Screamers 
are thought to be re¬ 
lated to the ducks, geese 
and swans.
