The trivialization of devices capable of recording ultrasound has enabled the recent years considerably increase the data collected. It is still important to note that species identification from audio recordings are not always reliable 100%, the cries of a Greater noctule may in fact resemble those of a Hound Cestoni (Tadarida teniotis) (Haquart & Disca, 2007).
trivialization wa vifaa na uwezo wa kurekodi ultrasound umewezesha miaka ya hivi karibuni mno kuongeza data zilizokusanywa. Bado ni muhimu kutambua kwamba utambulisho aina kutoka rekodi audio si mara zote kuaminika 100%, Kilio cha noctule Greater ili kwa kweli inafanana na wale wa Cestoni Hound (Tadarida teniotis) (Haquart & Disca, 2007).
