This call at around 10 PM yesterday night confounded me. Since it was in a territory of Ural Owls I thought it must be one their many calls. But then friends of mine recalled something called the "Devil's cackle" by Eagle Owls. It is an alarm call made by both the male and the female but you do not hear it often. Although I did not hear any Ural Owl in the recording, I wonder if it was an Ural Owl that made the Eagle Owl a bit nervous.
