Hi there! Heard this call from around 10pm right up till near 1am (and still going!)
Went to look in the woods but couldn't see anything, despite being right under the tree they seemed to be in!
Hopefully the video attachment works (you can't see anything, only audio)
Pretty sure it’s a Long-eared Owl. Attach a link for comparison.
