Transcript of Animal Communication
By the end of this lesson you should be able to
1. List the 4 main methods of animal communication
2. Describe and evaluate methods of communication for a given animal species.
Intended Learning Outcomes
How do animals communicate?
Methods of Communication
In what way is this Animal Communicating?
Visually Animals Communicate either through
Badges or Displays
Wolves and dogs put their tails between their legs and lie on their backs to show submission to another wolf or dog and to let them know they are not a threat.
When wolves (and dogs) want to show dominance they stare at each other, raise their fur and bare their teeth. This lets the other wolf or dog know that they want to be the top, or dominant, animal.
Animals make lots of different sounds to communicate. From the roar of a lion to the song of the whale, sound is a way for animals to "talk" to other animals.
Auditory communication is the sound an animal makes.
These sounds may be one that comes from the animal or it may be a sound an animal makes when it interacts with an object.
Male American alligators use combinations of sounds and displays to get the attention of females when they want to mate. They roar, slap their heads against the water and then tap the nose of the female, nudge her and shove up against her.
Different vocalizations for different occasions.
Coyotes use a series of barks, yips and howls to mark territory, and to let other coyotes know where they are.
Red squirrels will make a series of loud rattles, screeches and yips to warn off intruders
Lots of animals will vocalize when an intruder comes too close to or invades their territory..
Tactile communication, or touch, is an important form of communication for many animals.
Mother tigers lick and nuzzle their babies,
Chimpanzees groom each other,
Bear cubs wrestle with each other.
Touch is used to comfort, to establish dominance and to establish bonds
Many animals use chemical communication or pheromones to communicate.
They may leave their scent to mark territory or attract mates. They often use smell to find prey and identify other animals
Animals often use chemical communication to mark territory.
They leave pheromones, or chemical marks behind.
Some animals leave scent posts to mark their territory.
A scent post is something that is marked by an animal with its scent. Scent posts set the boundaries of an animal's territory
Have you ever seen a house cat rubbing its head up against someone? It is marking its territory! Domestic cats have scent glands near their mouths, on their foreheads and at the base of their tails.
Snakes use their forked tongues to "taste" or collect pheromones of prey animals that are in the air. They have receptors in the roof of their mouths that help them taste and smell the pheromones.
Ants use pheromones for more than just making trails.
A crushed ant emits an alarm pheromone that sends nearby ants into an attack frenzy and attracts more ants from farther away.
Several ant species even use "propaganda pheromones" to confuse enemy ants and make them fight among themselves
Ants communicate using pheromones
1. List the four main methods of animal communication.
2. Badges and Displays are both examples of which type of communication?
3. A lions roar is and example of visual communication. True of False?
4. Give an example of tactile communication from your class notes.
5. Ants following a pheromone trail is an example of what?
What’s your score?
In groups describe and evaluate the main methods of communication for one of the following animals.
Pass 9: Discuss how the senses are involved in animal communication
You will produce an illustrated essay to discuss how senses are involved in communication in a least two animal species. Visual, auditory tactile and chemical should all be mentioned.
