5 cf, 2 ?. Beida, Dinder, 13-14. II. 1911. 
This fine Swallow was common on the Blue-Nile and Dinder. I found 
a colony of nests, built on a lonely bank faceing the river at Beida, consisting 
of about twenty pairs. The birds were sitting on their nests and when I 
came near them they unwillingly left them, probaly because the incubation 
was progressed.
