Numbers in parentheses refer to the actual number of crashes at the specific position. With the landmark next to the hole (test trials) the bats rarely crashed at the previous position of the hole. With no landmark, the bats crashed into the net at a position different both from the previous position and from the opening in 14% (F1) and 16% (M2) of all crashes. No data were obtained for M1 with the landmark removed.
