I'm sure I can hear Nightjars churring with there sound in the background on the webcam of the Dartfort Warbler on the Minsmere heathland

i don't know whether anyone else can hear what I think is the churring sound of Nightjars in the background on the heathland on the Dartfort Warbler webcam on the BBC Springwatch website this evening. I'm sure I can.

Regards,

Ian.
