  • State of the World’s Birds is an annual review of environmental resources.
  • It is BirdLife International's flagship science publication.
  • According to the new review ‘State of the World’s Birds’, approximately 48% of existing bird species worldwide are known or suspected to be undergoing population declines.
  • The threat has been attributed to almost half of the 10,994 recognised extant species of birds to the expanding human footprint on the natural world and climate change.
  • The trend towards declining bird diversity is just as alarming in India, where recent annual trends have been calculated for 146 species.
  • Of these, nearly 80% are declining in numbers, and almost 50% plummeting strongly.
  • Just over 6% of the species studied show stable populations and 14% show increasing population trends.
  • Humans eat 14% of the world’s surviving species of birds.
