Abstract

119 Ceryle rudis were collected in the period from January 1970 to August 1971 in Zambia near Namwala on the Kafue Flats, and their food intake analysed. The only insect eaten to an appreciable extent was Anisoptera larva, which amounted to 24.1% by number. The most important fish were Alestes spp., 16.9%; Barbus spp., 16.9%; and Ciclidae, 32.3%, by numbers. The digestive stages of the stomach contents, combined with field observations, revealed that the birds feed 4 times a day. They regurgitate the indigestible remains between each meal. The average daily food intake approximated to 18.4 grams, or 24.6% of the body weight. Two hand-reared birds had a daily food intake of 26.5% and 24% of their body weight during the last 15 days before independence. The average number of fish eaten per day per bird was 7.2, of which 44% were Ciclidae.
