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 …

Despite major differences between human and avian colour vision, previous studies of
cuckoo egg mimicry have used human colour vision (or standards based thereon) to assess …

Avian brood parasites lay their eggs in other birds' nests, and hosts can mitigate the fitness
cost of raising unrelated offspring by rejecting parasitic eggs. A visually-based cognitive …

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 …

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 …

To investigate the evolutionary mechanism (host specificity vs. random searching)
maintaining mimicry between cuckoo egg appearance and that of different European cuckoo …

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 …

Many cuckoo species lay eggs that match those of their hosts, which can significantly reduce
rejection of their eggs by the host species. However, egg mimicry is problematic for …

Many hosts of the common cuckoo (Cuculus canorus) exhibit egg recognition, and reject
parasitic eggs. How do hosts discriminate cuckoo eggs from their own? Hosts might be able …
