A multi-thousand flock of Redbilled Quelea coming to drink. Perhaps at some signal, a small group of about 50 would alight on a mud spit, drink, then fly off to nearby bushes to wait for the others to have a turn. This procedure continued until all had drunk. By this time, the weight of these small birds caused the branches to be almost resting on the ground. Note the Fish Eagle (upper left corner) who was probably fishing in the same pond. I did not see the Fish Eagle, a raptor, try to capture any Quelea. [See next images].[Shinde Island, Botswanda].
