An experienced and most sharp-eyed of ornithologist find it difficult to recognize individual birds. Researchers have now developed artificial intelligence tool that can identify individual small birds.
The greatest limitation in the study of wild birds is that of recognizing individual birds. AI models are trained to recognize individual birds. For this the researchers collected thousands of labelled images of birds and then used this data to train and test AI models. After training the AI models were tested individual birds in wild populations of great tits and sociable weavers and a captive population of zebra finches. The AI had an accuracy of over 90 per cent for the wild species and 87 per cent for the captive zebra finches.AI methods similar to the one used in this study was previously used to identify animals at a species levels and individual primates, pigs and elephants.
The study was published in the journal Methods in Ecology and Evolution.
