Scores of flamingos have been found dead in western Kenya, reviving concerns that pollution is killing off the birds. The numbers of dead birds aren’t as high as in some past years — 40,000 flamingos died over three months in 1993 and 20,000 died in 1995 — but researchers say many of the remaining birds are sick. Ramesh Thampy of the World Wildlife Fund said the group had found that flamingos in the area were accumulating significant amounts of heavy metals in their systems. The lakes where the flamingos feed have increasingly become repositories for pollution, as Kenya and neighboring countries have expanded their industrial base and their use of fertilizers.
