It ’s looking like a smattering of the world ’s rare and most gorgeous snort species – including the brilliantly blue Spix ’s Macaw that inspired the animated movieRio – have latterly become nonextant in the wild .
A new study byBirdLife International , published in the journalBiological Conservation , has used a new statistical coming to value whether 51 barely - seen birds species have slipped into extinction over the past decade
At least eight razzing species should be added to the list of confirmed or suspect extinctions , harmonize to their findings . This doomed list includes the Alagoas foliage - gleaner , the cryptic treehunter , and the poo - uli , all of which seem to be wholly extinct with no individual stay on in the wild or even incarceration .

In old case of bird extinction over the past few century , the vast majority of victims be on humble islands . Although hunt and trapping often played a big part , they were most often driven defunctness due to an invasive species .
However , we ’re now seeing a dissimilar vogue . Most of these coinage have become extinct as a solvent of disforestation and home ground losses in Brazil and other mainland South American forest .
The raw enquiry project get over eight years of take scientific literature , reports of sightings , and information leave by experts . BirdLife International collected the determination in the hopes that the newfangled penetration will be used to inform and update theIUCN Red List , the go - to direct for fauna conservation status , which is often used to inform insurance .
" find the rate is unmanageable owing to prison term - lags in determine whether a species has been drop off – so there are probably additional mintage lose over the last decade or two that we wo n’t declare extinct for a few more age , " Butchart total .
Fear not , there was some vaguely affirmative newsworthiness from the study ( be monish , it ’s only a feeble glimmer of hope ) . The Moorea Reed - warbler of French Polynesia is currently lean as Critically Endangered ( Presumed Extinct ) , but the study recommend reclassification as Critically Endangered .
