- I think I have a barking owl or a frogmouth in my back garden in Lane Cove. I would describe the sound he makes as a lound, human like, reverberant two-syllable sound but the first is much less pronounced than the second syllable. He sounded a little like a machine until I got up and went down into the garden to locate him. I could only see a small black lump on the gumtree about the size of a small rockmelon. He is a regular visitor and I would like him to leave as it disturbs my sleep. Can you help with firm identification please?
