This book is aimed primarily at all scholars of evolution but particularly at those interested in
predator–prey interactions. In a nutshell, the objective of this book is to explore whether bats …

Obligate avian brood parasitic species impose the costs of incubating foreign eggs and
raising young upon their unrelated hosts. The most common host defence is the rejection of …

Mimicry of a harmless model (aggressive mimicry) is used by egg, chick and fledgling brood
parasites that resemble the host's own eggs, chicks and fledglings. However, aggressive …

Flounder change colour and pattern for camouflage. We used a spectrometer to measure
reflectance spectra and a digital camera to capture body patterns of two flounder species …

Advanced analyses of feathers, eggs, and other colorful tissues in ornithology collections
are revealing fresh insights into the life histories of birds. Here, we describe the methods …

Brown‐headed cowbirds (Molothrus ater) are generalist obligate brood parasites, laying in
the nest of nearly 300 avian species, and successfully parasitizing well over 100 host …

To date, only two pigments have been identified in avian eggshells: rusty-brown
protoporphyrin IX and blue-green biliverdin IXα. Most avian eggshell colours can be …

Aggressive mimic species use signals typically resembling an attractive or harmless model
to deceive other organisms in order to increase foraging success. With the exception of a …

Camouflage versatility is probably no better developed in the animal kingdom than in the
coleoid cephalopods (octopus, squid, cuttlefish). These marine molluscs possess soft …

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