Onon's successful return challenges existing perceptions about bird migrations by showcasing the remarkable capabilities of these seemingly ungainly birds like cuckoos. The extensive 26,000km round trip undertaken by Onon defies conventional expectations regarding land bird migrations, highlighting their impressive navigational skills and endurance. This successful journey demonstrates that even relatively small-bodied birds like cuckoos are capable of undertaking incredibly long-distance travels with precision and efficiency. By tracking Onon's journey and witnessing his safe return, researchers are prompted to reevaluate preconceived notions about bird migratory behaviors and capabilities in light of new evidence provided by this exceptional individual.
