Egg eviction imposes a recoverable cost of virulence in chicks of a brood parasite.

<h4>Background</h4>Chicks of virulent brood parasitic birds eliminate their nestmates and avoid costly competition for foster parental care. Yet, efforts to evict nest contents by the blind and naked common cuckoo Cuculus canorus hatchling are counterintuitive as both adult parasites and...
