Wolves can`t escape in sheep`s clothing any longer
London: It is possible to identify individual wild wolves with 100 percent accuracy with just their howls, a study has suggested.
Researchers from Nottingham Trent University, UK, have developed a computer program to help analyse eastern grey wolves` vocal signatures.
PhD student Holly Root-Gutteridge, who led the research, said that wolves howl a lot in the wild.
She said that with the help of the program it can be said with surety which wolf is howling, the BBC reported.
The team`s computer program analyses both volume (or amplitude) and pitch (or frequency) of wolf howls.
The scientists tested their program by studying dozens of archive recordings of wild eastern grey wolf howls, which lived mainly in Algonquin park, Canada, and collected by the British Library in London.
The team`s success rate was 100 percent when recognising individual wolves from their solo howls and achieved accuracy of 97 percent when they tried to identify wolves calling together in a `chorus howl.`
The findings have been published in the journal Bioacoustics.
