2.  Behavior: any way that an animal interacts with its
environment
 Includes finding food, ways that animals protect
themselves, make homes, find mates, and raise their
young
 Behaviors can be instinctive or learned
▪ Instinct: a behavior that an animal can do without ever learning
how to do it
▪ Inherited characteristics that don’t need to be learned and are always
performed the same way
▪ Dragonflies hunt by instinct
▪ Learning: a change in behavior that comes about through
experience
▪ A dog learns to go to the back door when it wants to go outside
▪ Young animals learn behaviors mainly from their parents

3.  Many behaviors help protect animals
from predators
 Opossums avoid predators by “playing
dead”
 Moths scare away predators by
opening their wings (they look like the
eyes of a fierce bird)
 Squids release a dark inky substance
into the water that blocks the
predators view
 Chipmunks protect themselves by
running away
 Cats raise their fur and arch their back
to look bigger and more dangerous
 Habit: a behavior that is learned
through practice

4.  Most animals do not
take care of their young
 However, birds and
mammals do
 Animals that live in
groups work together
for the good for the
group is called
cooperation
 Ex: insects that live in
colonies

5.  Migration is an
instinctive behavior
that means that
animals move to a
different place when
the season change
 In summer, many
birds nest and raise
their young in the
north and fly south
for the winter
▪ This is how they find
enough food to survive

6.  Communication: any behavior
that lets animals share
information
 Many animals communicate to
protect themselves from
predators and to attract mates
 Animals can communicate with
sounds, movements, smells, or by
other means
 Examples:
▪ Frilled lizards flare their frill when
they feel threatened
▪ Male birds sing to attract a mate
▪ Meerkats and monkeys use different
warning calls for different predators
