The legendary spooky call of Mottled wood owl. If heard in a scary setting it is bound to terrify many an unsuspecting soul. one of my school friends who visited kerala from Andhra back in 90s came running down from the first floor on hearing this. In many places it is considered to be a harbinger of death and I remember the older folks in the family cursing if it called anywhere near to the house. In reality the call is part of a pair calling to each other. This is usually followed by the pair calling to each other in typical style as in the link below.
Quality is poor -recorded with a Samsung mobile and the bird flew to its mate as it was calling out. Request Patra sab to see if it can be improved.
