Warning coloration of the "Brazilian Skunk" in The Colours of Animals [P 5] The basic concept of warning coloration (aposematism, like the black and yellow pattern of a wasp) is approached very simply: When an animal possesses an unpleasant attribute, it is often to its advantage to advertise the fact as publicly as possible.
In 1940, Hugh Cott wrote a compendious study of camouflage, mimicry, and aposematism, Adaptive Coloration in Animals. [6] By the 21st century, adaptation to life in cities had markedly reduced the antipredator responses of animals such as rats and pigeons; similar changes are observed in captive and domesticated animals. [79]
Animals use colour to advertise services such as cleaning to animals of other species; to signal their sexual status to other members of the same species; and in mimicry, taking advantage of the warning coloration of another species. Some animals use flashes of colour to divert attacks by startling predators. Zebras may possibly use motion ...
Animal coloration, readily observable, soon provided strong and independent lines of evidence, from camouflage, mimicry and aposematism, that natural selection was indeed at work. [ 6 ] [ 7 ] [ 8 ] The historian of science Peter J. Bowler wrote that Darwin's theory "was also extended to the broader topics of protective resemblances and mimicry ...
Active camouflage or adaptive camouflage is camouflage that adapts, often rapidly, to the surroundings of an object such as an animal or military vehicle. In theory, active camouflage could provide perfect concealment from visual detection.
In his textbook Adaptive Coloration in Animals (1940), Hugh Bamford Cott describes self-decoration under the heading "adventitious concealing coloration", also naming it "adventitious resemblance". He describes it as a device "perhaps unrivalled" for effective concealment, and points out that it is brought about and depends on "highly ...
Disruptive coloration by Hugh Cott, from Adaptive Coloration in Animals (1940) While trying to photograph a hen partridge on her nest, Cott waited for hours for the bird to return, finally taking some pictures of the empty nest before giving up. On developing the photographs, he realized the bird had been there all along, perfectly camouflaged ...
