Courtship behaviours are specialized patterns of behaviour that precede mating and reproduction in animals. 

The behaviour is carried out in sequence and each action is alternately performed by male and female animals, each step acts as a stimulus. 

In courtship the main process developed is communication. Communication can be developed by dancing, shaking, smell, and visual or auditory signals in different organisms. 

Types of Courtship Behaviour Pairing:

  • Display
  • Territoriality
  • Seasonal migration
  • Pairing

Pairing:

This is a type of reproductive behaviour in which a mature female and male leave their home and establish a new home elsewhere. This occurs when organisms leave their habitat in groups of two, one male and one female for the purpose of mating. The pairing may be very brief, in that it ends immediately after mating or may last for a lifetime. Pairing occurs in toads, winged termites, fishes e.g. Tilapia, Clarias etc.
