Cetti's Warbler in Autumn

Now I'm moored in yet another of my favourite spot, by the swingbridge at Sells Green. There are reed beds here where there's a small starling murmuration  in the winter; already there's a few around, and a group of 20 or so dropped into the reeds at 7:10 pm on Thursday. 

I've also been hearing something that sounded tantalisingly like a Cetti's Warbler. But their song (or rather, call; it's not exactly tuneful, as you can hear) is perfunctory and abrupt, and followed by silences that can stretch for some minutes.

Anyway, yesterday morning I heard it plain, as can you, gentle reader. It's that sharp, staccato burst you can hear about halfway through this recording, then again just before the end.

It's the first time I've heard one at Sells Green, and the first time I've heard one calling in autumn.
