Courtship Behavior

A behavior is the way an organism reacts to other organisms or to its
environment.

Courtship behavior is when an animal engages in different behaviors in
order to find a mate.

Behaviors are a form of communication. Animals can communicate
using sound, light, chemicals and body language.

There is a lot of competition to attract a mate. Sometimes animals
even bring gifts to each other.

Multiple Choice

When an animal engages in different behaviors in order to find a mate...

• innate behavior

• courtship behavior

• learned behavior

Protecting Offspring

Many animals build nests and dens to protect their young.
Animals build these out of a variety of materials for protection
from predators and the environment.

Another example of a nurturing behavior is herding. This is
when large groups of animals stay together and make sure
young animals are not left behind. Elephants take turn
watching each other’s babies so the mother can take breaks!

Some animals, such as the musk oxen, circle their young with
their horns facing out to protect them from predators. Bison
form two circles – the females make a circle around the young
and the males make a circle around the females.

Multiple Choice

How do animals prottect their young?

• herding

• building nests

• circling their young

• all answers are correct

Animals engage in
courtship behaviors:
dancing, singing, and
fighting, to attract a mate.

This keeps their offspring
alive.
Examples: Building a nest
or herding

Environmental factors:
diet, exercise, availability
of food & water, and
interaction with other
organisms determine how
an animal will grow.

Traits inherited from their
parents affect how the
animal grows.

that determine how
animals will grow. These
can either be
Genetic or
Environmental factors
