This is the African resident form of the common Kestrel, 

 and may be distinguished at a glance — in adult males at 

 least — by its darker and richer coloration and by its tail, 

 which always retains traces of the transverse black bars. 

 We have seen no Sudanese examples, but as we have 

 specimens in the Museum from Nigeria on one side and 

 Abyssinia and Somaliland on the other, we have little doubt 

 that it will be found to occur in the southern parts of our 

 region.

Widely distributed in winter in the Sudan. It is possible 

 that the eastern foi'm T. n. pekinensis also occurs, but we 

 hiive no positive evidence of it. It is distinguished by the 

 greater amount of blue on the wing-coverts of the male.
