The use of artificial stimuli in behavioral experimentation is pervasive and well precedented.
A perspective by Hauber et al.(2014) Ethology describes advantages of this approach and …

Signal detection theory addresses the challenge of successfully identifying informative
signals in noisy information contexts, allowing optimal behavioural decisions in diverse …

Accurate recognition of salient cues is critical for adaptive responses, but the underlying
sensory and cognitive processes are often poorly understood. For example, hosts of avian …

The arms race between brood parasites and their hosts provides a classic model to study
coevolution. Hosts often reject the parasitic egg, and brood parasites should therefore select …

Highlights•Egg rejection may vary with risk of brood parasitism spatially and
temporally.•Daurian redstarts are cavity-nesting hosts of cuckoos with two egg-laying …

Brood parasitic cuckoos and their hosts serve as model systems for studying host–parasite
coevolution. Egg-rejection behavior constitutes an effective defense against brood …

Interactions between avian brood parasites, such as common cuckoos (Cuculus canorus),
and their hosts are one of the best‐studied examples of the coevolutionary arms race …

Host–parasite dynamics involve coevolutionary arms races, which may lead to host
specialization and ensuing diversification. Our general understanding of the evolution of …

In species that are subject to brood parasitism, individuals often vary in their responses to
parasitic eggs, with some rejecting the eggs while others do not. While some factors, such as …

Experimentation is at the heart of classical and modern behavioral ecology research. The
manipulation of natural cues allows us to establish causation between aspects of the …
