A new estimate from researchers around the world has found 48 percent of living bird species are known or suspected to have declining populations.That's more than 5,000 species that face a risky future. Among the species surveyed, only 6 percent showed increases in population.
The recent estimates suggest similar patterns exist right across the planet, but especially in tropical, polar, and montane birds. In Costa Rica, which is famed for bird biodiversity, avian abundance has declined over the past decade. In Japan, there's a similar trend occurring among the brown shrike and the yellow-breasted bunting, which have lost huge parts of their range.
