My little owls heard the screams of other little owls and got started. And then I sat down to process the video. So Gnus and Yuya, hearing their voices in the recording, yelled even louder. It seems that this can go on indefinitely. I shot them from behind the wall, sticking out the edge of the phone.
These are territorial calls that house little owls use to designate their land and nesting area.
