For the first time, I believe, Marsh Warbler has bred in Suffolk. At a site near to Southwold, a pair was discovered by David Pearson, heard and observed only from private land; our observations up until the end of July have proven that the the pair were successful in raising three young, but as expected the birds have now departed and have not been seen for a week.
The male sang only intermittently, but we were able to watch it and also it's interaction with the female - quivering of wings and tail - in a small willow. The pair's routine, collecting food and regularly visiting a patch of reeds and nettles, strongly suggested breeding, and we were beginning to think that we would not be able to prove it. However, eventually we saw the male singing and then the pair feeding three small young in scrubby hawthorn bushes and in the reeds or nettles.
Initially, the small young were surprising warm in colour; come the end of July they were a lovely brassy colour (less warm above and a bit paler and ochreous below).
In the two attached images you can see one of the young being fed and also the male singing, note the primaries are bent up the reed stem, but still show prominent white tips.
