“Half of the birds of North America are at risk of extinction,” says Audubon’s chief scientist. That estimate is based on the 314 bird species, out of 588 studied, that could lose most of the area they currently occupy, because of a warming planet. Nearly 200 of these threatened species may find hospitable conditions elsewhere, but for 126 species there will be nowhere else to go, Audubon estimates in a report released yesterday. Shifts in climate could affect the range of grasslands, forests, and other bird habitats.
