Aposematic conspicuous coloration consists of one or a few bright colours, often in
combination with a black defined internal pattern. The function of conspicuousness in …

Conspicuousness is an important feature of warning coloration. One hypothesis for its
function is that it increases signal efficacy by facilitating avoidance learning. An alternative …

Two groups of male chicks (Gallus gallus) were allowed to peck at distasteful food (chick
crumbs flavoured with quinine and mustard) that either matched or contrasted with the …

Many prey species that are unprofitable (because they taste bad, are poisonous or are in
some other way defended against predators) are brightly coloured-a phenomenon known …

Colours are common stimuli in signalling systems. Requirements to function well as a signal
sometimes conflict between different signallers, and the same colour stimulus is used to …

Aposematic color patterns that signal prey unprofitability are suggested to work best when
there is high contrast within the animal color pattern or between the animal and its …

Many organisms use warning, or aposematic, coloration to signal their unprofitability to
potential predators. Aposematically colored prey are highly visually conspicuous. There is …

Many animals are toxic or unpalatable and signal this to predators with warning signals
(aposematism). Aposematic appearance has long been a classical system to study predator …

It has been suggested that the common existence of regular patterning in aposematic prey
animals makes them “stand out” from the background, improving detection and recognition …

Aposematic signals are often characterized by high conspicuousness. Larger and brighter
signals reinforce avoidance learning, distinguish defended from palatable prey and are …
