Animal identification through sounds

Animals make sounds all the time to communicate, attract their females, or as a warning of the presence of a predator. Use your senses of hearing and sight, and have fun knowing how scientists recognize animals that they do not see based on the vibrations of their calls, calculated with the use of a tool called a spectrogram. When listening to the sound, compare the frequencies of different animals and choose the best response.
