European nightjar wings sacrifice speed for hunting agility
Scientists at Lund University discovered that European nightjars trade flight efficiency for agility during their migration between Europe and southern Africa.
Wings optimized for slow hunting
Researchers found the bird's wings are not perfectly built for efficient high-speed travel. Instead, the structure prioritizes the ability to make sharp turns while catching insects. This design choice limits performance when flying at faster speeds.
Unique upward thrust technique
The study recorded that nightjars generate thrust during their upward wingbeat motion. Scientists noted this method was previously seen mainly in bats and insects. The birds use this specific technique to maintain control while hunting at low speeds.
Potential for new technology
The findings suggest these biological mechanisms could inspire future flying machines. Engineers might apply the upward thrust concept to improve drone performance. The research highlights a clear trade-off between migration range and hunting capability.
