  • Much of behaviour requires animals to communicate. Animals can communicate through a variety

  • of modes, which include chemicals, known as pheromones, sounds and signals, even dancing.

  • It can be defined as a behaviour of one animal that has an effect on the current or future

  • behaviour of another animal.

  • Communication between animals can imply messages or warnings. For example, plants send out

  • messages via pheromones to try and attract pollinators. Pheromones can be a hormone for

  • communication to the same species, for example to attract a mate or they can be a chemical

  • secreted by one animal to cause a reaction of another; they make communication possible.

  • Honey bees communicate information about food sources with a special dance, known as a ‘waggle

  • dance’. A figure of eight dance tells bees which direction and how far it is to flowers

  • and a round dance tells them that food is close by.

  • Sound from the dance of the bees is picked up by the tiny hairs on the bee’s head.

  • So bees communicate through sound, and movement signals, as well as by releasing pheromones

  • into the environment.

  • Killer whales communicate through sound. Sound is a very important method of communication

  • for whales because sight is less effective underwater. Killer whales produce whistles,

  • echolocation clicks, pulsed calls, low-frequency pops and jaw claps. Research has shown that

  • whales produce sounds more frequently when they are closer to other individuals, and

  • less frequently when groups are dispersed. It is thought that the sounds are used for

  • group recognition and the coordination of behaviour. It is also interesting to note

  • that each pod of whales has its own unique dialect.

  • Whales may also communicate using a variety of postures and gestures. However, the purpose

  • of behaviours such as breaching are not clearly understood, although it is assumed that behaviours

  • like jaw-snapping and head-butting communicate aggression.
