Scientists have long struggled with how to measure the effects of climate change on wildlife. This is especially true for birds flying in and out of coastal areas bordering the Arctic Ocean. In the past, researchers depended mainly on information gathered by satellite to follow the movement of birds and animals. But this method can be costly and result in huge amounts of information, which can be difficult to process.

Now scientists are turning to another kind of technology to help them follow birds and other wildlife. Songbirds are especially difficult to study in the wild. They can fly across thousands of kilometers and their bodies are too small for electronic tracking devices.

A new report tells about a project in which researchers recorded songbirds and then put the sounds into a computer program to be studied. The researchers created machine learning algorithms with the ability to focus on bird calls while ignoring other noises. The algorithm helps improve the likelihood of predicting the correct result. Similar machine learning methods have been used to recognize human speech.

Over the next 20 to 50 years, it will become harder to tell the (1) _____ between the human and the machine. All, body (2) will be replaceable. Computers will function like the human brain with the ability to recognize feelings and respond in a feeling way. They will then produce fake people. We will then be able to create a machine duplicate of ourselves so we will appear to be alive long after we are dead. Maybe a few decades later, a way will be found to transfer our spirit, including our (2) _____ and thoughts, to the new body. Then we can choose to live for as long as we want. It might be expensive. When it becomes possible to do a spirit transfer, they will figure out (3) _____ to do them automatically. So we will be able to reside within whichever duplicate we want, whenever we want.
