Birds habitats are moving north because of the global climate crisis.

WASHINGTON (Reuters) - Climate change is pushing American birds northward, with some finches and chickadees moving hundreds of miles (km) into Canada, an Audubon Society study reported on Tuesday.

Drawing on citizen observations over a 40-year period, the society's scientists found that 58 percent of 305 widespread bird species found in the contiguous United States shifted significantly to the north.

While there are many factors that can make birds move, there's no question this is caused by human-spurred global warming, according to report co-author Greg Butcher.
