The coevolutionary interactions between avian brood parasites and their hosts provide a
powerful system for investigating the diversity of animal coloration. Specifically, reciprocal …

Evading detection by predators is crucial for survival. Camouflage is therefore a widespread
adaptation, but despite substantial research effort our understanding of different camouflage …

Deals with all aspects of adaptive resemblance Full colour Covers everything from classic
examples of Batesian, Mullerian, aggressive and sexual mimicries through to human …

Predators have profound effects on prey behavior and some adult brood parasites use
predator resemblance to exploit the antipredator defenses of their hosts. Clarifying host …

Aposematic organisms warn predators of their unprofitability using a combination of
defenses, including visual warning signals, startling sounds, noxious odors, or aversive …

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

Mimetic resemblance is extensive across the tree of life yet agreeing on what constitutes
mimicry is challenging. One of the reasons for disagreement is a lack of unambiguous …

Background Resemblance to raptors such as hawks (Accipiter spp.) is considered to be an
adaptive strategy of cuckoos (Cuculus spp.), which has evolved to protect cuckoos against …

Avian brood parasites pose a serious threat to hosts, substantially reducing their fitness,
which selects for the evolution of host defences. A classic example of a host frontline …

Despite a recent explosion of research on pattern recognition, in both neuroscience and
computer vision, we lack a basic understanding of how most animals perceive and respond …
