Megabats use smell to find food sources like fruit and nectar.
They have keen senses of smell that rival that of the domestic dog.
Tube-nosed fruit bats such as the eastern tube-nosed bat (Nyctimene robinsoni) have stereo olfaction, meaning they are able to map and follow odor plumes three-dimensionally.

Along with most (or perhaps all) other bat species, megabats mothers and offspring also use scent to recognize each other, as well as for recognition of individuals.
In flying foxes, males have enlarged androgen-sensitive sebaceous glands on their shoulders they use for scent-marking their territories, particularly during the mating season.
The secretions of these glands vary by species—of the 65 chemical compounds isolated from the glands of four species, no compound was found in all species.
Males also engage in urine washing, or coating themselves in their own urine.
