The reciprocal interactions between brood parasites and their hosts provide models for
studying coevolution. For example, where hosts have evolved egg or chick discrimination …

Avian brood parasites and their hosts provide model systems for investigating links between
recognition, learning, and their fitness consequences,,,. One major evolutionary puzzle has …

To understand the co-existence of rejection and acceptance of cuckoo eggs within a host
population, the mechanism of egg discrimination and the cost-benefit balance of rejection …

Summary Some species of North American passerines nearly always reject nonmimetic
eggs placed in their nests and have apparently evolved this behavior in response to brood …

Evading detection by predators is crucial for survival. Camouflage is therefore a widespread
adaptation, but despite substantial research effort our understanding of different camouflage …

Reed warblers sometimes make recognition errors when faced with a mimetic cuckoo egg in
their nest and reject one or more of their own eggs rather than the foreign egg. Using the …

Many animals use concealing markings to reduce the risk of predation. These include
background pattern matching (crypsis), where the coloration matches a random sample of …

Many animals bear colors and patterns to reduce the risk of predation from visually hunting
predators, including warning colors, camouflage, and mimicry. In addition, various species …

Most previous studies of brood parasitism have stressed that host defences, such as egg
recognition, are lost in the absence of parasitism. Such losses could result in coevolutionary …

The coevolutionary relationships between brood parasites and their hosts are often studied
by examining the egg rejection behaviour of host species using artificial eggs. However, the …
