One of the most striking outcomes of coevolution between species is egg mimicry by brood
parasitic birds, resulting from rejection behavior by discriminating host parents. Yet, how …

Coevolutionary arms races are a potent force in evolution, and brood parasite–host
dynamics provide classical examples. Different host‐races of the common cuckoo, Cuculus …

Hosts of cuckoos have evolved defences allowing them to discriminate and reject parasite
eggs. Mechanisms of discrimination are mostly visually mediated, and have been studied …

Arms races between avian brood parasites and their hosts often result in parasitic mimicry of
host eggs, to evade rejection. Once egg mimicry has evolved, host defences could escalate …

How do birds tell the colours of their own and foreign eggs apart? We demonstrate that
perceptual modelling of avian visual discrimination can predict behavioural rejection …

Accurate recognition of salient cues is critical for adaptive responses, but the underlying
sensory and cognitive processes are often poorly understood. For example, hosts of avian …

Interspecific brood parasitism represents a prime example of the coevolutionary arms race
where each party has evolved strategies in response to the other. Here, we investigated …

Cuckoo–host interactions provide classical examples of coevolution. Cuckoos place hosts
under selection to detect and reject foreign eggs, while host defences result in the evolution …

Coevolutionary arms races are a powerful force driving evolution, adaptation, and
diversification. They can generate phenotypic polymorphisms that render it harder for a …

Some parasite cuckoo species lay eggs that, to the human eye, appear to mimic the
appearance of the eggs of their favourite hosts, which hinders discrimination and removal of …
