Abstract :
[en] Tanganyika Lake is frequented by many fish-eating birds, especially kingfishers. Our research has focused in particular on Ceryle rudis Linné, 1758, pied kingfisher. This study, conducted over a period of two months, from June 21 to July 19 and from August 19 to September 16, 2002, aims to analyze the fishery of pied kingfisher, considering fishing time during the day, before and afternoon. This bird was fishing from a perch or a hovering position. This regularly observed behavior allows the bird to fish in the pelagic water, which is uncommon in other species of kingfishers. This part distinguishes direct dives carried out from a perch and dives performed after a hovering position. Results show that, on a total of 583 dives, 324 or 55,5% were dives from perches while the rest were made from a hovering position. We found that Ceryle rudis is very active in fishing until midday and it is less so in the afternoon. The average number of fish eaten per day per bird was 9,3.
