Habits. Schomburgk states (Reis. Guian. iii. p. 741) that this 

 bird is only found on the Savannas. Its habits are the same as 

 those of R)ycter americana. It is supposed to nest in trees. The 

 " Macusis " and " Arekunas " call it Wohira. 



Mr. J. J. Quelch (Timehri (2) vi. pp. 125, 126) remarks that this 

 species is common, especially in the partially cleared lands on the 

 coast, and along the bushy tracts on such savannah creeks as the 

 Abary, are the Chimachimas or White-headed Caracaras {Milvago 

 cliimacliima) . Those birds are sometimes seen in the pastures on 

 the cattl ', which they frequent for ticks and insects, or on the 

 ground or bushes, where they seek out insects and small reptiles. 

 Often they occur in large flocks, though the individuals of such 

 groups generally perch at some distance apart.
