[Poland] Warsaw, 31 October, Eurasian Pygmy-Owl... (1 Viewer)

... and why not (apart from it being out of range)?
big city park, old-growth trees, grass, water, mouselike rodents galore, >= 3 tawny owls on site, one single call at 20:08 (sunset at 16:09)

TL;DR Here's a recording. No, the owl is gone.

I'm afraid it does not sound completely like Pygmy Owl to me. Too low and harsh. And Pygmy Owl usually calls in a series and well before full darkness.

An unusual Long-eared Owl, a day bird or some technology-made sound in a city park are possible.

 

[01101001]

Yes, I was thinking about the first and last of these possibilities. Regarding technology, the creak of the gate was much more grating, so the only plausible explanation would be a bus or perhaps a very loud bike. I can't see or hear the bus in the sonogram, though, and the sound does appear whistled rather than mechanical. I don't feel like being able to positively rule out a day bird, but a juvenile Long-Eared Owl would be off season by a long shot plus perhaps should have been more persistent in its begging (and even more shrill than the EPO's song)?

Admittedly, I could prove anything with anecdotal recordings, but here are two even lower-pitched Eurasian Pygmy-Owls (showing that the pitch can be relative or dependent on other conditions--maybe distance?):
ML485518171 Eurasian Pygmy-Owl Macaulay Library,
ML283837511 Eurasian Pygmy-Owl Macaulay Library.
But yes, the lack of repetitions now worries me too.

EDIT: The Royal Łazienki Park if it helps anyone.

... and why not?

Because there wasn't even a bird out there, let alone owl, let alone Eurasian Pygmy-Owl. Not. Ever.
The jury is still out on whether it was a bike or a car.

Hello,

my first feeling was "its a warning sound/signal" from a train. But the reason for this impression might well be the amplification/enhancement by the recording and/or editing and I am still unsure. I cant loose the feeling and I agree with you, that the train should be audible in your recording, too.

No offence you know.
