A lot easier to photograph than when in the reedbed!
No interactions present.
Good to know they're back down south - haven't seen or heard one this year, yet. One of my favourite birds - did you know that they are super mimics (I have heard 'sedgies' 'do': oystercatcher, redshank, yellow wagtail and common tern amongst others) and they have one of the most complex of all British birds' songs? I might be biased, spending four years studying them and their use of oilseed rape crops perhaps doesn't provide for the most balanced opinion on the subject.
Definitely a very interesting and entertaining species. I did know they had a complex, non-repeting song, but wasn't aware of their mimicing ability. I was watching & listening to these at Titchfield Haven (between Southampton & Portsmouth) yesterday and working on some alliterative mnemonics to keep the songs in my memory - 'sedge warblers are scratchy', 'reed warblers repeat'. Hmmm...
Last spring a Surlingham church marsh, I had a sedge warbler that routinely did 'blue tit' impressions.
