1. Behavioural adaptations: Since an animal's color and pattern usually reflect its behavior, behavioral modification allows many creatures to live in a disruptive environment. Birds have changed their breeding patterns, especially those that dwell close to humans, such as the common house finch (Carpodacus mexicanus). Other species have seen pressures to adapt feeding and migration patterns in response to changing environmental conditions caused by climate change, such as pollinators who must now adapt to changing conditions and flowering plants that must produce flowers at abnormal times when said conditions are best for them, thus affecting when these species emerge from hibernation to forage as well as when some species must begin annual migrations.
2. Color and pattern adaptations: Many animals utilize camouflage to conceal themselves from predators and prey, and it is a crucial aspect of their survival strategy. An animal's color and pattern usually reflect its environment; animals from different habitats might vary even within a particular population.
3. Defensive adaptations: The predatory pressure in an animal environment is reflected in its defensive adaptations. Animals modify their defensive efforts in response to variations in pressure. Rattlesnakes and their prey battle in an evolutionary context in which some common prey species develop resistance to their venom, forcing the snakes to rely on an alternative food supply, produce more potent venom, or perish.
