Animal Snoops

Communication between two animals

• does not exist.
• is similar to two people talking privately.
• is often loud or bright enough for other animals to hear or see.
• cannot be understood by other animals.

Biologists call animals' ability to detect each other's messages

• misbehavior.
• early warnings.
• eavesdropping.
• sneakiness.

Eavesdropping allows animals to

• teach other animals about themselves.
• learn more about people.
• become more intelligent.
• find food, a home, or a mate.

The noisy warning call of the go-away bird 

• makes it easy for a predator to catch it.
• also warns other animals that a predator is approaching.
• scares away all its predators.
• tells people to “go away.”

Most kinds of animals

• all eavesdrop on other animals in the same way.
• use only their hearing to eavesdrop.
• use different senses to do their eavesdropping.
• never eavesdrop on other animals.
