Nocturnal Bird Song?

[ottosump]

We have recently moved to a more rural location, I've always been fascinated by birds, their song, nesting habits, courtship etc. However I experienced a new nocturnal song, hard to describe really, I've tried to capture it on my recorder without much success. So I've downloaded the UK bird song app, its not on there, I've also searched the nocturnal bird song on the RSPB site but nothing sounds even similar to the sound I am hearing. Can anyone suggest what bird it can be then I can google the song, I've eliminated the following birds, Corncrake,Dunnock ,Nightingale,Nightjar,Reed warbler,Robin,Sedge warbler,Song thrush. It may help if I mention out location, we are in West Cumbria, near the town of Lowca CA286QT.
Kindest regards all

The only one I can think of is mgirating redwings which I've heard myself in late autumn. If your house is next to a street lamp it could be a robin.

[carrust]

Forget robin. I should read the OP properly

[Prudie]

Is it actually a song - a lot of variation in notes - or is it more a call or something repetitive?

[MyBlackHen]

The most lovely singer here is the blackbird.

[Milvus]

Have you tried Ring Ouzel, they are starting breeding in your area and further North

[jomifl]

can you give us an idea of what it sounds like, the nearest one to it on your list of eliminated supects would be a help.

Blackbird sub-song. It's a high pitched whistle that stays on the same note. They usually sing it from the middle of a shrub or bush.

Snipe can make some weird sounds with their wings just after dusk. Walking some paths in The Dales after dark could be quite scary unless you knew what caused these sounds.

[MyBlackHen]

"My" blackies sing beautiful songs, very varied, their best efforts are dusk and dawn, usually on the telephone pole, or next doors roof.
Could listen for hours.

I'll try to record again tonight, we have no street lights or any other artificial light for miles around, in the middle of acres of fields. Didn't hear it last night, hope it hasn't moved on.

Stone curlews have a wonderful call which they sometimes make at night - they are migrating now.

[heathfield]

Blackbird is quite likely. They keep varying their song, trying to show who's the best singer for any other blackbird that may be within hearing distance

[ottosump]

Cant get a recording due to the terrible weather we are having, the bird song sounds like long whoops differing in pitch, about 3 to 4 seconds long?

[jomifl]

Sounds like part of a nightingale song, does it do anything else, like trills and chirps.

[ottosump]

After much deliberation and searching I think I may have found it, the Lapwing. The audio clips I have googled have very similar sounds although not identical to what I heard. Quite an eerie noise late at night, thanks to all who replied, if I do manage to record the song I'll post.
Thanks again, Otto
