(1) For every obvious crossbill, razorbill, greenfinch, woodpecker, warbler, treecreeper, swift or flycatcher there is a mysterious wigeon, garganey, gadwall, bittern , siskin, pipit, shrike or twite.(2) A new process for recovery of Low Sodium Salt from bittern has been described in the present invention.(3) It is part of a Ôö¼├║4m project, half of which has come from the European Union, which will see bittern habitat developed at 19 sites throughout England.(4) The bittern , a brown heron, came close to dying out six years ago and conservationists feared there were only 11 ├ö├ç├┐booming├ö├ç├û males left.(5) This is curdled by calcium sulphate, or by a traditional curdling agent called nigari in Japan; this is bittern , the lye left over after the crystallization of salt from sea water.(6) The bittern has been transferred to a pen at the reserve which is home to the largest area of reedbed in the region.(7) You might even catch a glimpse of the reserve's most celebrated resident, the extremely rare and very shy bittern .(8) A combination of whey mineral and an alkali metal salt or bittern enhances the salty taste.(9) The bittern 's diet includes fish, amphibians, insects, worms, small mammals and even young birds.(10) Public viewing hides at the reserve and on the shores of the Bay offer glimpses of the rare bearded tit and bittern .(11) The oasis was my only source for waterfowl, and I spotted a little bittern , a moorhen and a pair of red-wattled plovers with their distinctive - if not extremely annoying - voice.(12) The bittern is one of the most threatened species in Britain - there are only 22 known pairs in the country.(13) The figures released today show the elusive bittern has become one of the UK's greatest wildlife success stories.(14) Areas already under stewardship have seen a marked increase in previously declining bird species, including the stone curlew, bittern , lapwing, reed bunting, greenfinch, pipit, twite, and wagtail.(15) An expert warden will be on hand to help you find the elusive bittern and then it's back to the tearoom for a hearty bowl of soup.(16) Stretch your legs and breathe in some crisp seasonal air on a winter walk around the beautiful RSPB Leighton Moss Nature Reserve in search of the elusive bittern , next Wednesday at 10.30 am.
