Animal sexual behaviour

Animals have different kinds of sexual behaviour. They use it to find a mate and reproduce. For example, a male bird may show off its colour and styling to attract a female. A fish might do special swimming or jumping to get the attention of a female in the water. Some animals also change their colour, sound or smell to attract a mate. All this behaviour is designed to help the animals get together so that they can have babies.
