Hi Mark, yep, yours sounds the same, though cwith better definition and tone colour than my LS10 ;) Glad to get the ID on that sound, it's puzzled me elsewhere!
Hi Ermine. Have just posted a Whitethroat doing the same thing on my blog. Seems they start with the churring and then go into proper song. Can't think of other species that I've heard doing this.
I think this is the alarm call of a whitethroat, followed by the regular song ot a whitethroat. The bird was sighted but without visual aids. A chiffchaff also barges in on this heathland recording, the picture is what it looked like though there's been a heath fire since the picture and the recording
