Drones built to look like birds evaded detection at Air Force tech exercise

A bird-shaped, wing-flapping drone evaded detection during a September 2026 Air Force technology exercise at Edwards Air Force Base. Made by U.S. company Ornadyne, the O1 imitates a crow’s appearance and flight rather than using propellers, making it quieter and more likely to be mistaken for wildlife by people and counter-drone sensors. At the “Game of Drones” event, it was tested against detection systems supplied by other participating companies; Ornadyne said those systems identified it as a bird rather than a drone. The exercise is a recurring effort to assess unmanned aircraft and counter-drone technologies in realistic, wargame-inspired scenarios.

The one-pound O1 can reportedly fly more than an hour and travel up to 10 kilometers, carrying a small payload such as a surveillance camera. Its design aims to blend into local bird populations: the company says it can alter the drone’s color, wingspan, proportions, and silhouette to resemble species found in a given region. This approach differs from other evasion methods, such as obscuring electronic signals or following autonomous routes. Bird-mimicking aircraft are part of the broader ornithopter category, which uses flapping wings rather than propellers or jets; China’s military has also shown a sparrow-like drone. The demonstration highlights how drones that exploit ordinary wildlife patterns could complicate detection, though the reported result concerns a specific test and sensor setup.
