Abstract

Three hypotheses are advanced to explain the damage to crops caused by Quelea quelea: 1) non-availability of wild gramineous seeds, which are usually the normal quelea food| 2) ready availability and ease to access to crops| 3) marked preference for crops. Cage experiments on food choices among some of the most frequently eaten seeds, demonstrate quelea's preference for seeds of the size of millet. Since seeds of this size are scarce in the quelea habitat, this suggests that quelea would tend to damage crops, even if wild grass seeds were abundant.
