Interactions between avian brood parasites, such as common cuckoos (Cuculus canorus),
and their hosts are one of the best‐studied examples of the coevolutionary arms race …

In the coevolutionary interactions between avian brood parasites and their hosts, egg
recognition based on color and/or pattern is a common and effective defense to counter …

Background Nest parasitism by cuckoos (Cuculus spp.) results in enormous reproductive
failure and forces hosts to evolve antiparasitic strategies, ie, recognition of own eggs and …

Most studies exploring abilities of hosts to detect brood parasitism are based on detecting
colour and/or pattern differences among parasitic and host eggs or nestlings, while only few …

Eggshell recognition in parental birds is vital for nest management, defense against brood
parasitism, optimal embryonic development, and minimizing disease and predation risks …

The puncture resistance hypothesis suggests that thick-shelled eggs of parasitic birds can
resist puncture-ejection by the host. However, few experiments have yet been conducted to …

Obligate brood parasitism is a peculiar behaviour found in some bird species. The costs for
their hosts can be high, generating selection for active defence strategies including foreign …

Egg recognition and rejection is a common and effective anti-parasitism adaptation in bird
hosts. Hosts reject alien eggs using recognition signals such as egg ground color and …
