As few as 250 grey-breasted parakeets, which are native northeast Brazil, are believed to remain in the wild.
Three of the rarest parrots in the world have hatched at Chester Zoo.
October 2013. It's only the second time grey-breasted parakeets have ever been bred in a UK zoo - with both breeding successes being at Chester.
Just 250 birds left alive
As few as 250 grey-breasted parakeets, which are native to Ceará in northeast Brazil, are believed to remain in the wild. Habitat loss and the illegal pet trade are blamed for their devastating decline. However the new arrivals have given conservationists fresh hope in the fight to haul the species back from the brink.
"These little additions are very significant indeed," said Andy Woolham, Chester Zoo's team manager of parrots and penguins. "Chester is the only zoo that works with grey-breasted parakeets in the UK and we're absolutely thrilled that we've been able to breed them, not least because there is real concern about the long-term future of the species in the wild.
