Scientists are turning dead birds into drones to study aerodynamics.
Researchers think that by creating avian drones using taxidermy birds, they can not only learn about flight but eventually use the drones to monitor wildlife.
"Actual bird wings also contain bones," Hassanalian said."We've found that artificial materials don't have the same efficiency."Through trial and error, the researchers learned that this experiment could work only with real bird wings, so the team obtained materials from web retailers such as Amazon and Etsy, which sell bird wings, and also acquired whole birds from taxidermists. Then, they attached parts of the taxidermy birds to electric motors.
In agreement with earlier research, "we discovered that when birds are flying in a flock, those in the middle section preserve their energy more than in the front," Hassanalian said."Their efficiency improved by 44%."
