Present for its second day - does this earn it an extra accolade?

Of the 114 reports in this 11 year period, the top locations are:
Somerset (esp Steart) - 6
Weymouth area (esp Lodmoor & Radipole) - 12
West Cornwall (esp Marazion) - 13
Isles of Scilly - 9
Shetland - 6
South Wales (esp Kenfig & Uskmouth) - 12
South Devon (esp Slapton, South Milton & Thurlestone) - 12
Portsmouth area (esp Farlington & Titchfield) - 10
East Kent - 7
Despite the fact it should be a good part of the country my region (East Anglia) seems to be largely shunned by this species. Shame.
How useful as an ID feature are the pointed tail feathers?

Hi Phil,
I would say of limited value in the field: a Sedge Warblers feeding in wet grass is just as likely to have pointed-looking tail feathers at times. The rufous rump and overall darkness of your bird also suggest Sedge to me. There is much variation in overall colour tones with both Aquatic and Sedge, some juvenile Aquatics seem very pale and yellowish while others can be rather darker. Sedgies range from bright pale yellowish to much richer, rufous brown individuals and at this time of year many of them have a more or less pronounced central crown stripe (just broad, brighter pale fringes to these feathers rather than solidly pale). Lots of Aquatics have a narrow pale crown stripe that is often partially hidden by the blackish lateral crown stripe feathers so be careful if you come across a candidate with or without the central crown stripe. Basically a combination of criteria are required to clinch the genuine article. I often find the best feature to look for on a possible Aquatic are the pale lores which contrast well with the dark patch (of variable shape) behind the eye.
Both species, to me in any case, have a very different "character" or personality from each other. Aquatics often seem rather gentle, sometimes shy but curious. In the nets they are generally quiet, a bit "zen" (!), rarely struggle much during extraction and rarely make any noise. Sedge on the other hand are boisterous, more like a hyperactive teenager, perhaps more likely to just perch in view for just a second or two before disappearing into cover again. They usually much more active during extraction too and frequently make noises of discontent. These are all very personal impressions so sorry it they seem a bit vague !
All reedbed birds such as acrocephalus warblers are somewhat secretive and you only ever see a fraction of the number of birds present in the area on a given day as any ringer can confirm. The key to locating an Aquatic Warbler is habitat; get the right habitat and stake it out if you want to have any chance of finding one. We carried out radio-tracking last year on a number of individual AWs and they seemed to spend their active feeding time in the rushy / wet grassland areas before retiring to the nearby reedbed to roost, etc. ( p.25, Bilan du camp de Baguage Donges 2011 on http://www.acrola.fr/publications.html). If the conditions / habitat allows it then very slowly walking through the rushy areas making soft tongue-clicking "tuk" noises has worked for me in the past.
Jane, without doing a forensic examination of your photo I'd say it looks spot-on for an Aquatic ! :t:
Continued good luck to all of you

PS: some more blurry, normally unpublishable photos attached to illustrate some of the above !
Present for its second day - does this earn it an extra accolade?
I took this this morning. I'd heard a promising call about 1/4 mile south of where yesterday's bird was. Having spent most of the intervening daylight hours getting drenched watching twitching reeds and having no photographic or other evidence to show for it, I pulled out my video camera - which has a great microphone on it. As I was getting ready a bird popped briefly into view. I pressed the photo button and the bird flew off. I only saw it in flight... and it flew a long long way back towards the north end of the marsh, looking streaky and pale. Not having any reading glasses to hand, I couldn't see what I'd taken, but another birder said it looked promising. Now reunited with my glasses it does look promising, though the photo is pants and full of artefact.
Had a nice yellow Sedgie this morning, with especially clear mantle lines... but look at the lores and the flaring upwards super.
