Chalinolobus morio     CHMO

Characteristic frequency between 46 and 53 kHz depending on locality. Curved with often visible down sweeping tail. Consecutive pulses often show slight alternation in shape and energy. They sometimes appear irregular and in pairs.
Can generally be distinguished from other species calling at similar frequencies (as Vespadelus vulturnus) by a down sweeping tail which is often present in search phase calls.

The feeding buzz. The calls here are full of energy; some are overloading the electronics.
