L‘écologie et la vie sociale du Céphalophe bleu (Cephalophus monticola Thunberg), petit ruminant forestier africain


Laboratoire d'Ecologie Générale, 4 Avenue du Petit Chǎteau, F-91800 Brunoy.


The blue duiker is a small, frugivorous, strictly diurnal ruminant that occupies forest with open undergrowth. The social group consists of a ♂-♀ pair with the young of the last two litters. Pairs seem permanent in small territories adjacent to each other, without any noticeable overlap. The population density is high.

The life style adopted by the blue duiker represents an exception among forest ruminants, and appears to be a well adapted response to various ecological pressures, especially predation.
