Neiva Maria Robaldo Guedes

Neiva Maria Robaldo Guedes, or Neiva Guedes, (born Ponta Porã, 10 December 1962) is a Brazilian biologist and a specialist on environment and species conservation.

In November 1989, Neiva came across a flock of hyacinth macaws in the Pantanal and, knowing that they were in danger of extinction, she began to work on cataloguing and conserving the species with her own means. Illegal capture for the pet bird trade, habitat destruction and feather collection for handicrafts were the main reasons for the drastic reduction in hyacinth macaw numbers. Provided by Wikipedia
