The Giant noctule is the largest bat species of Europe; it has mostly a Mediterranean distribution. Spanish colleagues thought they may feed on migratory passerines based on feathers found in their droppings in spring and fall. This surprising diet has been confirmed by stable isotopic analyses carried out in collaboration with our lab.
