Smell of green leaf volatiles attracts white storks to freshly cut meadows

Abstract Finding food is perhaps the most important task for all animals. Birds often show up unexpectedly at novel food sources such as freshly tilled fields or mown meadows. Here we test whether wild European white storks primarily use visual, social, auditory or olfactory information to find fres...
