AI-Altered Bird Photos Threaten Citizen Science Data

- Researchers warned in a Nature commentary that hundreds of fake or AI-altered bird images have already surfaced on citizen science databases including iNaturalist and Macaulay Library, with the true scale unknown.
- Dr. Alexander Lees, an ecologist at Manchester Metropolitan University and lead author, said a huge volume of wildlife photos shared on Facebook are now AI-generated, making it difficult to use such images to track species in space and time.
- AI editing tools can inadvertently introduce features of different bird species when users ask them to enhance a photo — e.g., removing an obstructing branch — leading to false sightings such as a red-winged blackbird reported in central Brazil that was actually an epaulet oriole.
- iNaturalist has flagged only 1,400 of its more than 610 million images for AI use, though the platform's director of community support Tony Iwane said most cases are likely unintentional rather than malicious hoaxes.
- Citizen science platforms serve as real-time sensors for ecological change — tracking whether plants are flowering early or species are shifting north with climate warming — making data accuracy critical for conservation decisions, per Iwane.
Why it matters: Citizen science platforms like iNaturalist, with over 610 million images, feed directly into peer-reviewed research on species range shifts driven by climate change. Even well-intentioned AI edits that blend features across species can silently corrupt that record, meaning a tool meant to sharpen a photo can erase or invent a species at the edge of its range.
