The arrow-marked babbler lives in social groups of between 3 and 15 birds (six being the average) that defend large territories, with the size of the territory being dependent upon the number of individuals in the group. They feed on insects, spiders, and sometimes snails and lizards, as well as fruits. Foraging occurs near the ground, sometimes in association with other babblers or bulbuls. A dry gurgling babble “gra-gra-gra-gra-gra” is given by multiple birds, keeping the group together.
