AbstractA census and preliminary observations on the ranging and feeding behavior ofGalago senegalensiswere made in a savannah‐woodland site in Kenya. Population densities in three slightly different habitats were all approximately 1.5 animals/ha. Ranging patterns suggested the existence of territorial behavior. The diet of the galagos was exclusively insects and gums of two species ofAcacia. The gum ofA. drepanolobiumappeared to be preferred to that ofA. xanthophloea. The chemistry of the gums suggests that this preference is not due simply to the total level of phenolics or to avoidance of condensed tannins but may relate to the presence of compounds (e. g., flavonoids) having nutritional or hormonelike actio
