This study reports on demography and dispersal patterns of wild Kinda baboons (Papio kindae) of Kasanka National Park over a period of 38 months. These data come from the first long-term project to study Kinda baboon behavior. Given their phylogenetic proximity and ecological overlap with the yellow baboon (Papio cynocephalus) we tested the hypothesis that Kinda baboons would exhibit comparable demographic and dispersal patterns. Demographic data presented here were first collected in 2010 and continued through September 2014. Group size fluctuated over the study period between 65 and 54 individuals. The number of non-natal adult males ranged from 4-7, and the number of adult females ranged from 15-17. Female interbirth interval ranged from 15 to 27 months with an average of 22.3 months. Females began exhibiting sexual swellings at approximately 5 years of age. Forty-three infants were born during the study period. Infant mortality (death within the first year) over the study period was 17%. Over the study period, 14 adult males disappeared or emigrated while 4 males immigrated into the group. Five females, 3 juveniles, and 7 infants disappeared and were presumed dead from natural causes, predation or poaching. This study shows that Kinda baboons are female philopatric and male dispersing, as is the case in most other “savanna baboons” including yellows. General demography of the study appears to be similar. Further analysis of the social structure of this Kinda population will shed light on the similarity and differences seen between Kinda and other baboons.
