The study of parasites and their likely influence on optimal foraging and mate-selection in animals has attracted much attention in recent times. The possible effects of parasites on the host include the manipulation of host behaviour by parasites and the emergence of host behavioural adaptations for protecting against parasitism. Self-medication in wild animals is believed to be the behavioural adaptation evolved primarily against parasites and associated diseases. In this article, we have briefly reviewed some types of unusual behaviour observed inmammals, birds and insectswhich can be considered as self-medication.
