Hidden in a wooden hut, a group of bird-spotting ornithologists peer through binoculars at the Royal Society for the Protection of Birds (RSPB) rreserve at Rainham Marshes, Essex England. Watching dozens of wintering birds, the group are intensely looking through their optical equipment in anticipation of seeing rare breeds at this Site of Special Scientific Interest (SSSI), a wetland alongside the River Thames, 20 miles from Central London. A narrow slit is open to keep them hidden from sight so leaning on elbows and with a guide sheet in front to identify particular species, they concentrate on their hobby. The RSPB has 200 nature reserves covering almost 130,000 hectares, home to 80% of Britain's rarest or most threatened bird species. Its role is to speak out for birds and wildlife, tackling the problems that threaten the environment.
