Eight avian species go extinct

Eight species of avian have become extinct this century, statistical analysis by BirdLife International has said. These include the spix’s macaw, the cryptic treehunter, and the poo-uli. Scientists involved in the study warned that an extinction ‘crisis’, fuelled by human behaviour, was exploding across continents. Earlier this year, the International Union for the Conservation of Nature red list assessed that more than 26,000 of the world’s species were under severe threat. These extinctions have all taken place over various points this century. The spix’s macaw, for instance, is said to have been wiped away in 2000.
