Bill and cere yellow; feet yellow, claws black ; iris 
reddish brown. 
These Kites are so common as to be a considerable 
nuisance in camp. They seem only to be present in the 
country from about the beginning of August to the end of 
March. When on the Upper Lufupa R., in September 1907, 
I saw many hundreds of these birds together, apparently on 
their southward spring migration.
