August seems a very early date for these birds to be on 

 migration. This species seems to be uncommon in the 

 Sudan. In fact, we can find no notice of its occurrence 

 since Heuglin's record, though the Museum possesses one 

 other example from Sennar. 



Butler states, however, tliat it is widely distributed in 

 winter from Khartoum to the Lado Enclave.
