Abstract :
[en] Lake Noukoué in southern Benin, is heavily exploited fishery, but it is also inhabited by numerous piscivorous birds, escpecially kingfishers. This study considers the similarity between the diet of kingfishers and fish available on the local market between mid-February to mi-May 1999, durng a low water level preriod. Excretory pellets were collected on the top of breeding banks and inside brood chambers. The diet was determined by comparing the bones recovered from the pellets with a reference collection. Eighteen prey categories were recognised in the 1099 diagnostic items. Kingfishers preyed mostly on cichlids (Sarotherodon melanotheron Rüppell and Hemichromis fasciatus Peters), clupeids (Ethmalosa fimbria (Bowdich)), eleotrids (Kribia sp.) and Hyporhamphus picarti (Val.). Prey size of H. fasciatus ranged from 22 to 73 mm (46.4 +/- 11.6 mm) and S. melanotheron from 24 to 65 mm (44 +/- 9.2 mm). The compositionof the diet varied depending on time and location. Overlap with marketed fish is limitid to S. melanotheron.
