A research team of Professor Jean-Louis Justin of the French National Museum of Natural History examined the habitats of the fruit body in France based on the 111 records recorded mainly from volunteers from 1999 to 2017 It was. As a result, at least five types of exotic falcons were discovered in France. And it seems that two of them are new species.
