I realise that describing bird song in words is fraught with difficulties... but while I was on a futile wait for pine martens in the Trossachs in Argyll (UK) last week, I heard a bird song which I can only describe as like a woodwind reverberation. I've not heard anything like it before - the closest is the bittern's boom, but the repetition was more rapid and although low was nowhere near as low. It only every occurred in deep twilight, both dawn and dusk, but I heard it quite frequently. I was sitting in woodland, but there was also a small river and marshland in the general direction of the sound.
