Successful conservation and management strategy of wild animals usually starts by assessing their population size. This is of particular relevance in areas submitted to long periods of human conflicts which is the case of Burundi. A census of chimpanzee populations was made throughout Kibira National Park between September 2011 and February 2013 to provide reliable information on density estimates of chimpanzees inhabiting the forest. The method was based on marked nest counts from line transects which allowed the calculation of population densities of all weaned individuals. We recorded a total of 471 chimpanzee nests in four sectors of the park (Mabayi 290 nests, Rwegura 68 Teza 65 and Musigati 48). We derived an estimate of the total population of 203 (122-339) weaned chimpanzees in the whole park. We discuss that result in perspective of necessiry of future research on chimpanzees in Burundi. First, implementation of a monitoring program of chimpanzee is necessary to constitute a database, as well as collecting data of tree phenology on which chimpanzee depend. Second, an effective transboundary strategic plan to conserve Kibira-Nyungwe as one landscape is necessary to maintain viable population of chimpanzees. [less ▲]

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. [less ▲]
