Egg size is a widely-studied trait and yet the causes and consequences of variation in this
trait remain poorly understood. Egg size varies greatly within many avian species, with the …

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

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 …

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

Coevolutionary arms races, where adaptations in one party select for counter-adaptations in
another and vice versa, are fundamental to interactions between organisms and their …

Coevolutionary arms races between brood parasites and hosts involve genetic adaptations
and counter-adaptations. However, hosts sometimes acquire defenses too rapidly to reflect …

The risk of cuckoo Cuculus canorus parasitism for great reed warbler Acrocephalus
arundinaceus nests was evaluated in respect to nest and nest site structure in the reedbeds …

I examined ecological and behavioural variables influencing the susceptibility of red-winged
blackbird, Agelaius phoeniceus, nests to brood parasitism by brown-headed cowbirds …

The interactions between brood parasitic birds and their host species provide one of the best
model systems for coevolution. Despite being intensively studied, the parasite–host system …

Farmland birds belong to the most endangered group of vertebrates in Europe. They are an
important component of farmland biodiversity considering the numerous functions they …
