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 {Perms'). 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 wing-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.
