The campo flicker builds its nest in an anthill. The campo flicker does eat ants, but I didn't find any references that mention it nests in anthills. The closest thing I found was termite mounds. From here: "This woodpecker may nest both in trees in wooded areas, and in mud banks and termites mounds in treeless regions."

The giant anteater's main diet is ants.

And the maned wolf defecates on the ant nests. Specifically, the leafcutter ants.

Eh..

A shared hobby!

That's right! I wanna hurry up and unleash my wild side!

Seem like a huge misalignment in preference...
