Pollution may have caused the deaths of up to 50,000 flamingos on Kenya’s Lake Bogoria, which has the biggest concentration of flamingos in the world, conservationists say. Gideon Motelin of Kenya’s Egerton University conducted tests on some of the corpses littering the shores of the lake and found that they contained nine or 10 heavy metals . Motelin said, “It is not normal to find arsenic, lead, mercury, chromium, and copper in the livers and kidneys of these birds.” Enviros believe the source of the pollution is large-scale farms near Lake Nakuru, about 60 miles south of Bogoria, an area that the flamingos abandoned two years ago.
