Mr. Percival was the first to discover the occurrence of 

 this rare crepuscular Hawk in East Africa. It is closely 

 related to the Honey-Buzzards (Pernis). It was observed 

 at dusk on several occasions, flying very swiftly over 

 Mr. PercivaPs house in pursuit of bats, but in the bad 

 light it was extremely difficult to procure specimens.

Specimen 257 is an interesting example; it has almost 

 attained the plumage of the adult male, the secondaries and 

 greater wing-coverts being rufous barred with black, and 

 the outer tail-feathers buff barred with black. 



[During the plague-outbreak in Nairobi I had charge of 

 a quarantine camp on the edge of the Kikuyu Forest. Every 

 night at sundown a flight of small Hawks used to pass, and 

 one night I managed to secure three birds, two of which 

 belonged to this species. — A. B. P.]

 Dr. Reichenow does not appear to recognise C. amurensis 

 as distinct from C. vespertina, though it is a perfectly dif- 

 ferent species : the adults are easily distinguished by the 

 colour of the under Aving-coverts ; in C. vespertina these are 

 grey-blue, and in C. amurensis white. 



This specimen was shot in company with two of the last- 

 named species, flying at sunset.
