  • Mating Behaviour
    • Frogs, whales and birds make a song or call to attract a mate. It is usually the male who makes the call to attract the females
    • Chemical: Pheromones (sexual attractants)
      • Females who produce the chemical to be detected by a male who can follow the trail
        • E.g. Moths use pheromones
    • Male deers fight each other and only the winner gets to mate
      • Instead of real fighting, the fights often involve displays, which indicates strength
    • Courtship displays involve the males doing a special display to impress the female
      • E.g. exaggerated posturing, dancing and showing brightly coloured parts of the anatomy
        • Courtship displays are species-specific, so the female knows she is mating with the right species
          • Often a link between the impressiveness of the display and the fertility of the male
    • Most animals have more than one mate
      • In most species, the male takes no part in the birth/care for the young - he'll then go off and mate with other females during the same mating season
      • Some birds, the male will mate with one female one season and not the same one from year to year
      • Some mammals, a male may have a group of females which he mates with them all. The females are known as his 'harem'
      • Monogamy (staying with just one mate): e.g. birds and mammals
  • Frogs, whales and birds make a song or call to attract a mate. It is usually the male who makes the call to attract the females
