Animal communication is the transfer of information from one or a group of
animals (sender or senders) to one or more other animals (receiver or receivers)
which aects either the current or future behavior of the receivers.
Communication is sending and receiving information between two or more people. The person
sending the message is referred to as the sender, while the person receiving the information is
called the receiver. The information conveyed can include facts, ideas, concepts, opinions, beliefs, attitudes, instructions and even emotions.
Types of Communication
Methods of communication vary, and you are almost certainly familiar with all of them. Let's
take a look at some of the primary methods.
• Verbal communication is simply sending a message through a spoken language that isunderstood by both the sender and receiver of the message. Eamples of verbal
communications include face!to!face talking, listening to a lecture or seminar, and
listening to a television program. "n fact, if you are listening to this lesson, you areengaged in a verbal form of communication.

• #ritten communication is sending a message by the use of symbols that are understood
by both the sender and receiver of the message. "f you are reading the transcript of this
lesson, you are engaged in written communication.
• $ody language is a form of nonverbal communication that can be used to send a message.
%ou can often tell if your boss is pleased or upset simply by looking at his facialepressions, posture and gestures. &or eample, a flushed face may mean embarrassment
a clinched fist may indicate anger and the rolling of one's eyes may signal disbelief orannoyance.
ANIMAL COMMUNICATION AND LANGUAGE

Natural Animal Communication
3earce )*+45, p161 cites a definition of animal communication by 7later )*+48, see 3earce for
reference, which we will also use as a working definition in this lecture!9nimal communication is :the transmission of a signal from one animal to another such that the
sender benefits, on average, from the response of the recipient:.
This loose definition permits the inclusion of many types of behaviour and allows
:communication: to be applied to a very large range of animals, including some very simpleanimals.

• learnt from others
Language
7ome linguists )eg 2homsky, *+65, Macphail, *+41, both cited in 3earce, *+45 have argued thatlanguage is a uni-ue human behaviour and that animal communication falls short of human
language in a number of important ways.
2homsky )*+65 claims that humans possess an innate universal grammar that is not possessed
by other species. This can be readily demonstrated, he claims, by the universality of language inhuman society and by the similarity of their grammars. ;o natural non!human system of
communication shares this common grammar.
Macphail )*+41, cited by 3earce, *+45 made the claim that :humans ac-uire language )and non!
humans do not not because humans are )-uantitatively more intelligent, but because humans possess some species!specific mechanism )or mechanisms which is a prere-uisite of language!

7ome researchers have provided lists of what they consider to be the criteria that animal
communication must meet to be regarded as language.
&or this lecture the list devised by /ockett )*+=> is utilised, although this list is not the onlysuch list available. 7uch lists tend to be -uite similar and certain elements of the /ockett list are
considered particularly important in evaluating the -uestion :can animals be taught language0:
/ockett's thirteen :design!features: for language are as follows!
*. Vocal-auitory c!annel" sounds emitted from the mouth and perceived by the auditory
system. This applies to many animal communication systems, but there are manyeceptions. 9lso, it does not apply to human sign language, which meets all the other *1
re-uirements. "t also does not apply to written language.
1. #roacast transmission an irectional reception" this re-uires that the recipient can
tell the direction that the signal comes from and thus the originator of the signal.
8. $api faing %transitory nature&" 7ignal lasts a short time. This is true of all systems
involving sound. "t doesn't take into account audio recording technology and is also not
true for written language. "t tends not to apply to animal signals involving chemicals andsmells which often fade slowly.

?. Interc!angea'ility" 9ll utterances that are understood can be produced. This is different
to some communication systems where, for eample, males produce one set of
behaviours and females another and they are unable to interchange these messages so thatmales use the female signal and vice versa.
6. Total fee'ac(" The sender of a message also perceives the message. That is, you hearwhat you say. This is not always true for some kinds of animal displays.
=. )pecialisation" The signal produced is specialised for communication and is not the sideeffect of some other behaviour )eg. the panting of a dog incidentally produces the panting
sound.
5. )emanticity" There is a fied relationship between a signal and a meaning.
4. Ar'itrariness" There is an arbitrary relationship between a signal and its meaning. That
is, the signal, is related to the meaning by convention or by instinct but has no inherent
relationship with the meaning. This can be seen in different words in different languagesreferring to the same meaning, or to different calls of different sub!species of a single
bird species having the same meaning.
+. Discreteness" Language can be said to be built up from discrete units )eg. phonemes in
human language. Echanging such discrete units causes a change in the meaning of a

signal. This is an abrupt change, rather than a continuous change of meaning )eg. :cat:
doesn't gradually change in meaning to :bat:, but changes abruptly in meaning at some
point. 7peech loudness and pitch can, on the other hand be changed continuously withoutabrupt changes of meaning.
*>. Displacement" 2ommunicating about things or events that are distant in time or space.$ee dancing is an eample of this.
**. *roucti+ity" Language is an open system. #e can potentially produce an infinite )1 number of different messages by combining the elements differently. This is not a feature
of, for eample, the calls of gibbons who have a finite number of calls and thus a closed
system of communication.
*1. Traitional transmission" Each generation needs to learn the system of communicationfrom the preceding generation. Many species produce the same uniform calls regardless
of where they live in the range )even a range spanning several continents. 7uch systems
can be assumed to be defined by instinct and thus by genetics. 7ome animals, on the other hand fail to develop the calls of their species when raised in isolation.
*8. Duality of patterning" Large numbers of meaningful signals )eg. morphemes or words
produced from a small number of meaningless units )eg. phonemes. /uman language is

very unusual in this respect. 9pes, for eample, do not share this feature in their natural
communication systems.
ommunication s mportant
#hen you need to convey something to someone, you communicate with them. This is the
process of individuals sending, receiving, and responding to a signal. There's really no other way
to ask your friend for a ride home, tell your mother you love her, or ask your dog to get off the
couch. %ou have to send out a signal, the receiver has to get that signal, and then, hopefully, they
respond@
2ommunication is not a one!way street, nor is there Aust one way to communicate. 9nimals
communicate with each other using signals that are visual, auditory, chemical, and electrical. Thetype of signal used depends on the message being conveyed, the environment, and the animal
sending the signal. Most animals do not rely solely on one type of signal. "nstead, they utili

*isual "ignals
There are an incredible number of different types of visual signals used in animal
communication. Cust think of the many various ways you can make a face to epress your
feelings, and you'll see what " mean.
Visual signals are most often used during the day because they simply can't be seen in the dark of
night. 9nimals, like birds and humans, use visual signals because they're active and awake
during the day and can easily see these types of signals being communicated. Visual signals
come in the form of bright colors )like bird feathers and specific body movements )like
someone holding their hand up to say 'stop'. 7ome animals even send a signal by changing color
during courtship or aggression.
"n a-uatic environments, visual signals often serve as territorial displays. 7ome fish puff up like a
balloon to make themselves appear bigger )and therefore scarier, while others may 'charge' at an
intruder to show their willingness to defend their home.
Visual signals may be beneficial in situations where other types of signals would be dangerous. "f
the sender of a signal can communicate that a predator is nearby without saying a word, this may
enable those individuals to avoid being eaten without the predator ever knowing it was spotted.

+uditory "ignals
7ound is another good way to send a message, and this can be effective when individuals are too
far away to see visual signals. %ou hear a pack of wolves long before you see it, and this is for a
very good reason ! they want you to stay far away@
Dther times, auditory signals are used in courtship displays or to invite mates into a territory.
9uditory signals may be used to defend a territory if the owner feels threatened.
9uditory signals can be helpful if an individual becomes separated from the rest of the group.
%ou are more likely to yell for help if you are lost in the woods than to wave your arms around
hoping someone will see you. %our cry travels much farther than your visual arm waving, so the
chances of being found are much greater with an auditory signal in this situation.
hemical and ,lectrical "ignals
9 chemical signal is an effective way of communicating if you need to send a signal but don't
plan on sticking around for the receiver's response. Many animals use chemical signals, such as
scents, to mark territories. This way, they can mark a large area without having to constantly
patrol the border to ward off intruders. The scent acts as a ';o Trespassing' sign, warning others
that the area already belongs to someone else.

2hemical signals may also be used to communicate beneficial information to other members of
the group. &or eample, when worker honeybees bring back pollen from a patch of flowers, they
regurgitate it to communicate to the other bees what it tastes and smells like. This will help the
other bees identify that same pollen when they're out foraging.
Forms of Animal Communication
*isual ommunication
Visual communication for animals comes in two forms badges and displays. $adges, the color
and shape of the animal, are structural adaptations, such as the bright yellow feathers of the male
9merican goldfinch. The bright colors tell a prospective mate that the male is a suitable choice.
isplays are the behaviors animals ehibit, such as the glow of a firefly to attract mates or when
a dog wags his tail to let you know he's happy.
Visual communication is the least effective since the animals must be close enough to see one
another.
+uditory ommunication
$arking, growling, hissing and purring all are considered animal auditory communication.
7ounds can be used to attract mates, ward off threats and epress happiness or pain.

&or eample, dogs bark when approached by a stranger. (ed s-uirrels use a series of rattles,
screeches and yips to warn intruders to stay away. 9nd dolphins use auditory communication to
set themselves apart from others !! a uni-ue whistle that also helps them locate food.
$actile ommunication
Like humans, animals can rely on tactile communication !! touch !! to convey messages. Most
animals use this form of communication to show affection, comfort or fear, or even to establish
dominance. &or instance, horses will kick each other to ward off threats or when competing for a
mate. 9s kittens, cats will nu
