In World War II, did people with bird feeders have substantially different chirping friends than we see today?
Probably not, but a group of researchers warns than 2075 might look a lot less like then, or even 1975, or today. The distribution of birds in the United States could change a lot.
A new U.S. Geological Survey study in
predicts where 50 bird species will breed, feed and live in the conterminous U.S. by 2075. While some types of birds, like the Baird's sparrow, could lose a significant amount of their current U.S. range, other ranges could nearly double.
