Can AI identify bird species from a 1-second audio clip ?

Cornell's Merlin app made this a standard tool for birders. The model knows more bird calls than any single human ornithologist.

AI systems can identify bird species from audio clips, including those as short as 1 second, with a reasonable degree of accuracy. This is made possible through the use of machine learning algorithms, particularly deep learning models, that are trained on large datasets of bird calls. These models can learn to recognize patterns in the audio signals that are unique to specific bird species, allowing for accurate identification. The performance of these systems can be further improved by incorporating additional information, such as the location and time of year the recording was made.
