I only met with this rare Bee-eater in the Lofu Valley, 
south of Lake Tanganyika. It has the habits of a Melitto- 
phagus rather than of a Merops , making short flights and 
constantly returning to the same perch. It haunts the edges 
of dense forests. I never saw it hawking high in the air as do 
M. apiaster and M. natalensis. It is not at all shy.
