Display Behavior
Display behaviour is a set of ritualized behaviours that enable an animal to animal communication, communicate to other animals (typically of the same species) about specific stimuli. These ritualized behaviours can be visual however many animals depend on a mixture of visual, audio, tactical and/or chemical signals as well. Evolution has tailored these stereotyped behaviours to allow animals to communicate both conspecifically and interspecifically which allows for a broader connection in different niches in an ecosystem. It is connected to sexual selection and survival of the species in various ways. Typically, display behaviour is used for Courtship display, courtship between two animals and to signal to the female that a viable male is ready to mate. In other instances, species may exhibit territorial display behaviour, in order to preserve a foraging or Predation, hunting territory for its family or group. A third form is exhibited by tournament species in which males will f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feather Of Male Pavo Cristatus (Indian Peafowl)
Feathers are epidermal growths that form a distinctive outer covering, or plumage, on both avian (bird) and some non-avian dinosaurs and other archosaurs. They are the most complex integumentary structures found in vertebrates and a premier example of a complex evolutionary novelty. They are among the characteristics that distinguish the extant birds from other living groups. Although feathers cover most of the bird's body, they arise only from certain well-defined tracts on the skin. They aid in flight, thermal insulation, and waterproofing. In addition, coloration helps in communication and protection. Plumology (or plumage science) is the name for the science that is associated with the study of feathers. Feathers have a number of utilitarian, cultural, and religious uses. Feathers are both soft and excellent at trapping heat; thus, they are sometimes used in high-class bedding, especially pillows, blankets, and mattresses. They are also used as filling for winter clothin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
