Pets

Hollydoves nest in holly bushes, using the spiny leaves to deter predators from their eggs. They are extremely commonly targeted by Mistledoves, who replace Hollydove eggs with their own, although this relationship does not seem to have had a negative effect on the Hollydove population.

Variants

Mistledoves are a brood parasite that primarily target Hollydove nests, replacing Hollydove eggs with their own to be raised by the other birds. The two species are not closely related, but their hatchlings are near indistinguishable from one another.
