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).
