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 …

Coevolutionary theory predicts that the most common long‐term outcome of the
relationships between brood parasites and their hosts should be coevolutionary cycles …

At first sight just a small brown bird, the dunnock's unobtrusive appearance belies its
extraordinary behaviour and mating patterns. In this book Nick Davies gives a full account of …

(1) There was no difference in the distinctiveness of egg markings between species that
have interacted strongly with cuckoos and species that have not, nor in intra-clutch variation …

An examination of about 12000 clutches of European passerines that contained eggs of the
common cuckoo (Cuculus canorus), held in museum egg‐collections, revealed statistically …

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 …

Because hosts that accept a parasitic egg laid by the common cuckoo, Cuculus canorus, are
unlikely to fledge their own offspring, rejection should be an adaptive response. Evidence …

The interactions between avian interspecific brood parasites and their hosts provide
tractable and informative systems for investigating coevolution. Generally, these …

The brown‐headed cowbird (Molothrus ater) is a widespread, obligate brood parasite of
North American passerine birds. In southern Manitoba, where hosts are sympatric with …

In this study, I quantified the removal of eggs by the Brown-headed Cowbird (Molothrus ater)
from parasitized Yellow Warbler (Dendroica petechia) nests. Laying cowbirds removed one …
