Wild Symbiosis: You scratch my back, I scratch yours

Many wild creatures of different species share a symbiotic relationship, where their interaction is a benefit to both species. Let’s see images of live wild animals (in the wild in their natural habitat) prominently showing in the image two or more wild creatures of two different species whose symbiotic interaction with each other is of mutual benefit. INCLUDE in the subject or notes section; the two species of wildlife AND the general location in which the photograph was taken. NO CAPTIVE animals such as in zoos or artificial enclosures.
