Summary: White pelicans Pelecanus onocratalus were recorded breeding on the Etosha Pan for the first time in 1971. The breeding colony of c. 3000 pairs was situated on flat, dry ground. The nearest water for fishing was 100 km distant, at Lake Oponono, and the pelicans used lifting air thermals to glide there and back. Disturbances elsewhere caused the pelicans to abandon two earlier nesting attempts and were probably the reason why they chose the isolation of the Etosha Pan. An attempted rescue of some chicks when significant mortality occured near the nests, was largely unsuccessful. Notes on nests, eggs, behaviour of adults and young, scavengers and presence of insecticides in the eggs are given. The fledging success of young hatched was 40 per cent. In addition the status Pelecanus onocrotalus is discussed
