The calling behavior of male B. variegata from Omis, sample 1 (1,2) and sample 2 (3,4) shown just at the end of call (1,3) and during interval (2,4); 5 calling male from Plitvice during an interval. of air from the buccal cavity into the lungs, which expand further in the pro- cess. The males call in a restricted area for several hours and especially after sunset. Few calls were heard in the morning and during the day. The calling male changes its calling site only when there are disturbances in the water pro- duced by other toads or after disturbances from outside. When there were two calling males in the pool (45 cm x 25 cm x cm) of the experimental terrarium the calling was never antiphonal; instead, the toads defended their territories. But when the two calling males were in different.
