Possible Marsh Warbler?

Hey there folks,

Hope everyone is well.

We were out at Stodmarsh Nature Reserve on Saturday and whilst the highlight of the day was catching a fly-by of the Purple Heron there at the moment, scanning through my pictures tonight I came across this little fella.

I was wondering if we've been lucky enough to chance upon a Marsh Warbler?

I've a couple of images which are very similar and this is probably the best of the two but, my hopeful positives are:

  • Summer visitor
  • Especially to Kent
  • Seen at Stodmarsh so right environment
  • Very prominent and bolder eye-ring

Anyway, just thought I'd post and see if you fine folk (and experts :)) could help settle the matter?

Many thanks for your help,

Mark
