Only met with twice on our Bahr-el-Ghazal journey, in 

 clearings in the forest ; but the country is not well suited to 

 its habits. The male was nearly in full plumage, the female 

 immature.

In the Bahr-el-Ghazal I found the Common Wheatear 

 abundant everywhere except in thick forest from Meslira 

 to Chak Chak. The bird shot at Mayik was in very 

 worn and grey plumage, and very white on the under 

 surface.

This dark-coloured Wheatear was common on the plain 

 between Meshra and Ayum, but not noticed anywhere else. 

 The birds were generally in pairs and had a habit of hovering 

 in the air somewhat like Bush-Larks. 



124. Saxicola melanoleuca (Giild.). 

 a. S. Khartoum, 2.10.07. 



Noticed twice at Khartoum in October 1907. This is 

 the Eastern Black-throated Chat [Saxicola melanoleuca 

 typica), with the entire throat from chin to breast black.
