840 BIRDS OF SOUTH AFRICA. - 
Mr. Ayres writes: ‘‘One morning, very early, I went down to the 
river with my rod to fish, and sitting quietly near an extensive 
bed of reeds and rushes, I saw many hundreds of these little 
Martins leave their roosts among the rushes, all together, just as 
the sun rose; about a quarter of an hour later many hundreds of 
C. paludicola left the same patch of reeds, or others close by, all 
together, or nearly so; at this time the two species were not 
mixed, but at other times of the day they are nearly always 
together, coursing for insects.’
