This AI tool can identify individual birds with 90% accuracy

Birdwatchers armed with field glasses and fields books can be excellent at identifying species, but they struggle to recognize people in a flock.

Fortunately for them, a new AI tool can do a difficult job for them – and potentially provide new insights into bird behaviors.

Researchers first trained the AI on identified pictures of wild great tits and sociable weavers, in addition to captive zebra finches. They then tested the system on brand-new images of the exact same birds that it had never ever seen prior to. The team says the AI properly-recognized over 90% of the wild species and 87% of the captive ones.

“We reveal that computers can regularly acknowledge dozens of individual birds, even though we can not ourselves inform these people apart,” stated Dr. André Ferreira of the Center for Practical and Evolutionary Ecology (CEFE), the lead author of the study.

“In doing so, our study offers the methods of overcoming one of the greatest limitations in the research study of wild birds – dependably acknowledging people.”

Structure of the system

Manual techniques of identifying birds- such as connecting colored bands to their legs to tell them apart – can be difficult for the animals and time-consuming for scientists.

AI tools can offer a less intrusive alternative, but they still need to be trained on a large number of labeled images. In the human acknowledgment systems utilized by Facebook, this isn’t a huge issue, as users willingly upload and tag millions of their photos every day. Animals are less likely to share their personal snaps.

The researchers conquered this problem by constructing bird feeders with camera traps and sensing units. Most of the birds they studied are fitted with electronic tags, comparable to the microchips placed in animal canines and felines. When the feeder’s sensors detected among these tags, they set off the electronic cameras to take a picture. Eventually, the system constructed up a dataset big enough to train the AI to spot the birdies in the wild.

The group confesses the tool has some significant restrictions. It can just re-identify people that it’s been shown prior to, and it might have a hard time to spot birds if their appearance modifications, such as when they shed plumes. They think that bigger datasets will get rid of these challenges.

Ultimately, the system’s capability to identify specific animals could improve the long-lasting monitoring of birds and assist protect them from threats such as environment modification. And for amateur ornithologists, it could one day be another helpful tool in their birdwatching package.
