Warning Coloration

Adaptations For Survival

1-25-19 gray screech-owl _u1a9516Mimicry, warning coloration and camouflage are three of the many ways in which animals have adapted in order to survive.

Mimicry, when an animal looks or acts like another organism, is illustrated by the Viceroy butterfly which looks remarkably like a Monarch. Warning coloration often makes predators aware of an organism’s toxicity – Red Efts are a prime example. Camouflage, or cryptic coloration, where an animal resembles its surroundings in coloration, form or movement, is exemplified by Eastern Screech-Owls. Not only is their color pattern that of tree bark, but they often stretch upwards and freeze in an upright position, closing their eyes to prevent reflection in their eyes from announcing their presence to predators or prey.

Eastern Screech-Owls come in three color morphs, rufous ( gray, and (rarely) brown. (Thanks to Marc Beerman and Howard Muscott for photo op.)
