Climate change alters habitat for migratory birds in California, Idaho
Every year, millions of waterbirds migrating from Alaska to Patagonia take a break from that epic journey to rest, eat and breed in a stretch of wetlands spanning six Western states called the Great Basin. A warming climate has made that migration more challenging by altering how mountain snowmelt flows into the network of lakes and rivers stretching from the Sierra Nevada to the Rockies, according to a new study.
