Animals Defend Their Territory

Spraying
Spraying (also known as territorial marking) is behavior used by animals to identify their territory. Most commonly, this is scent marking, accomplished by depositing strong-smelling chemicals such as urine at prominent locations within the territory. Often the scent contains carrier proteins, such as the major urinary proteins, to stabilize the odors and maintain them for longer.
Not only does the marking communicate to others the same species, but it is also noted by prey species and avoided. For example felids such as leopards and jaguars mark by rubbing themselves against vegetation. Some prosimians, such as the Red-bellied Lemur, also use scent marking to establish a territory. Many ungulates, for example the Blue Wildebeest, use scent marking from two glands, the preorbital gland and a scent gland in the ho.
