Recognise a Chirping Bird
How many times we have heard bird sounds and found it difficult to recognize them? Grant Van Horn, a researcher at Cornell University has now created the Merlin Bird app that can recognize sounds of more than 400 species of birds of the USA and Canada. It uses artificial intelligence to identify each species, displaying in real-time a list of photos of the birds that are singing or calling. The researchers made the app work by treating the sounds as images and apply new and powerful image classification algorithms. Merlin’s pioneering approach to sound identification is powered by tens of thousands of citizen scientists who contributed their bird observations and sound recordings to eBird, the Cornell Lab’s global database.
