ID Problems

I received the following email and photograph from an old friend Ian Best this morning

Howard,

This bird landed on Paul Kennerley's boat about midday yesterday and remained completely helpless and apparently tame ! Catherine handed it over to me - I kept it overnight and today - as texted - it seemed to make an amazing recovery - so was obviously exhausted !! Sorry pictures so bad - she was livening up fast by now !! Hopefully they are good enough to identify ? Have now released it into the garden as you suggested and it is now perched happily in one of the trees.
Ian

I have tentatively put it down as a Reed Warbler Acrocephalus scirpaceus but as we all know ID from photographs has its own problems so I could be wrong - would welcome any comments -
But a nice story anyhow
