Many putative examples of coevolution do not stand up to critical analysis. A rigorous
definition of coevolution requires that a trait in one species has evolved in response to a trait …

Animal camouflage represents one of the most important ways of preventing (or facilitating)
predation. It attracted the attention of the earliest evolutionary biologists, and today remains …

Birds as brood parasites lay their eggs in the nests of other kinds of birds; these" hosts"
incubate and rear the young. In the Old World, cuckoos have long been known as brood …

Incubating new ideas about avian reproduction/SJ Reynolds & DC Deeming--The fossil
record and evolution of avian egg nesting and incubation/DC Deeming--Nest construction …

MATERIALS AND METHODS The artificial cowbird eggs used in the experiments are similar
in size and pattern to typical real cowbird eggs (fig. 1). The latter average 21.45 x 16.42 mm …

I suggest that the cuckoo's parasitic adaptations are of two kinds:'trickery', which is how adult
cuckoos and cuckoo eggs and chicks evade host defences, and involves adaptations that …

In most birds and mammals, young are raised in family groups. The phenotypes of
nestmates and parents are thus reliable cues for recognition of conspecifics and kin …

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 …

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 …

The interactions between avian obligate interspecific brood parasites and their hosts provide
tractable systems for studying coevolutionary processes in nature. This review highlights …
