Bird call at night

Question

Can someone help identify this bird call? I've tried many avenues but without success. Thank you in advance. 
 And how do I attach the sound file?

To identify a bird call, day or night, you can search for an online site, of which there are many. Two to mention are: 
 Click here for RSPB and use the search box 
 Click here for Bird Song UK 
 Alternatively, you can use one of many apps via Google Play or The App Store on a smartphone 
 One which some of the regulars here use is the Merlin Bird App . The RSPB also have an app to identify birds with. 
 
 Finally, to upload a file, depending on your text/reply box layout, look for the Insert tab, located either at the top or bottom of the text box, then follow the instructions below 
 
 Select " Insert " 
 Select " Insert image/video/file " 
 Where it says " From " select the source, " Web (URL)/File upload/Community search " 
 When you've made your selection, select " OK " to post/upload, or if you've selected the wrong file/link etc, then select " Cancel " 
 To select the next file or link, start the above process again and for subsequent uploads.

If you use " Web (URL) ", then all you need to do is insert the link 
 When you've made your selection, select " OK " to post/upload, or if you've selected the wrong file/link etc, then select " Cancel " 
 To select the next link, start the above process again and for subsequent uploads.

I hope the above helps.
