Did you know that we can learn a lot about animals by listening to the sounds they make?

The Carajás National Forest is a protected region in the Brazilian Amazon. Scientists have been recording audio to monitor the animals of this forest and study how climate change might impact them.

So far the researchers have analyzed more than 7,000 minutes of audio recordings. They have been able to identify more than 230 bird species, in addition to mammals, amphibians, and insects.

Sit back and listen to the amazing sounds of the Amazon!

The study of animal sounds is called bioacoustics. Scientists place microphones in the environment so they can record and listen to the sounds of nature. They can also monitor how these sounds change over time. Audio recordings are analyzed with the help of computer algorithms. This exciting new technology can help us learn new things about animals and how to conserve them.

Some things we can learn using bioacoustics:

  • which animals are present (biodiversity of the area)
  • how animals use the landscape
  • how animals interact
  • how animal sounds change over time
  • how animal sounds change in response to climate change, deforestation, or other impacts
