Study uses microphones to eavesdrop on the secret lives of birds

The team used BirdNet, a machine learning tool, to identify birds in the recordings and verified recordings of American goshawks to understand how birds respond when a goshawk calls. According to the study, birds called and sang less after an American goshawk called, but where along the roughly 420-mile span of the Sierra Nevada the birds lived affected how much they changed their behavior. Birds farther south in the Sierra Nevada sang and called less often in the presence of a goshawk than birds farther north.
