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

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

A long‐standing question in animal communication is whether signals reveal intrinsic
properties of the signaller or extrinsic properties of its environment. Alarm calls, one of the …

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 …

Alarm calls are interesting for both proximate and ultimate reasons. Because of their usually
close connection with relevant events in the environment, they can reveal much about the …

Many birds utter alarm calls when they encounter predators, and previous work has
revealed that variation in the characteristics of the alarm, or “chick-a-dee,” calls of black …

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