Other times, like in the case of the monkeys mounting the deer, the propositioned species doesn't seem to mind.
Some interspecies sex can be beneficial to the surviving offspring, if they are genetically close enough (this depends a bit on how you define "species"). These groups of animals can come together and make brand-new creatures. Coyotes and wolves make coywolves, and grizzly bears and polar bears make "grolar bears."
Sometimes, the new species have different beneficial genes from both of their parents, and are able to survive better. Once, a single finch from one Galapagos island flew to another island and started a hybrid population between two finch species.

Sex Between Different Animal Species Is Fairly Common
Mammals, birds, reptiles, amphibians, and even insects will have sex outside their own species.
