Either way, a blue-and-yellow macaw that zookeepers named Juliet is believed to be the only wild bird of its kind left in the Brazilian city where the birds once flew far and wide.
Blue-and-yellow macaws live to be about 35 years old and Juliet – no spring chicken – should have found a lifelong mate years ago, according to Neiva Guedes, president of the Hyacinth Macaw Institute, an environmental group.
Aside from Juliet, the last sighting of a blue-and-yellow macaw flying free in Rio was in 1818 by an Austrian naturalist, according to Marcelo Rheingantz, a biologist at the Federal University of Rio de Janeiro, and there are no other types of macaws in the city.
