1. What does Suzuki’s work suggest Japanese tits can use to communicate (beyond just sounds)?

Only loudness and pitch changes
Only body movement, not calls
Only songs used for mating
Specific words and even grammar

2. By around what day do the chicks begin to understand the meaning of different alarm sounds?

Around day 30
Around day 5
Around day 15
Around day 10

3. When Suzuki tested the snake near another nest, what did the chicks do after the “jar jar” call?

They evacuated the nest within seconds
They ignored it and stayed quiet

Communication across species/regions and “grammar” tests (05:58 – 11:30)

Transcript will load here…

1. In the park experiment, how did the tree sparrows respond when “Pittsby” (alert/hawk) was played?

They moved closer to the speaker
They kept looking for food with no response
They immediately took off into the trees
They began building nests

2. What happened when Finnish researchers played the reversed call order to the Finnish tits?

They attacked the speaker
They did not react/approach the speaker
They approached the speaker the same way
They sang a new call back

3. What did Suzuki’s two-speaker vs. one-speaker test suggest about how the birds process the calls?

They interpret the two words when played consecutively from the same speaker
They only react to volume, not meaning
They cannot distinguish any call order
They prefer hearing calls from two directions at once

Do birds lie? Understanding across animals and a message to humans (11:30 – 14:21)

Transcript will load here…

1. What did the tit birds sometimes do when faced with larger predators like crows?

They stayed completely silent to avoid attention
They made the hawk signal even when there was no hawk
They only used the snake alarm call
They stopped using alarm calls altogether

2. Which non-bird animal does the video say can also understand the tit birds’ calls?

Fish
Deer
Squirrels
Frogs

3. According to the speaker, what do we need to begin understanding animals?

A laboratory and complex models
Advanced equipment and artificial intelligence
A curious mind and a lot of patience
A phone app that translates sounds

1. What is the main idea of the video?

Bird calls are random sounds with no meaning
Only humans can learn alarms and warnings
Predators cannot be detected by sound in forests
Some birds use meaningful calls and structured combinations that function like language

2. Which piece of evidence best supports the idea of “grammar” in the calls?

Birds only call when they are hungry
The calls are louder in winter
Birds respond only when calls are played in a correct order
Different forests have different trees

3. What broader message does the ending emphasize?

Paying attention to animals can change how we see the world
Nature is too complicated to observe without technology
Only scientists can notice animal behavior
People should avoid forests because animals are dangerous

After 20 Years, This Scientist Changed How We Understand Bird Language

Do you think animal calls can be called “language”? What is your definition of language?
Which experiment in the video felt most convincing to you, and why?
Is using a false alarm call to scare away a predator an example of “lying,” or just survival behavior? Explain.
How could people “turn their eyes to nature again” in a city or suburban neighborhood?
