- Why necessary?
- successful courtship helps lead to offspring with maximum chance of survival by:
- recognising members of own species
- mating only occurs between same species so fertile offspring
- Identify mate capable of reproducing
- Shows sexual maturity both can breed.

- Pair helps lead to successful mating and raising.
- Synchronise mating
- so it takes place when max probability of sperm and egg fusing
