A new study by the University of Illinois Urbana-Champaign suggests the long-term effects of climate change could create a higher risk of extinction for certain bird species.

Between 1980 and 2015, researchers studied more than 400 general and specialist bird species across North America. While a general species can thrive in various environments, specialist birds can only live in specific conditions.

Madhu Khanna, professor of environmental economics at the university, said the data show climate change affects migratory birds and specialist birds at greater rates than the general bird population.

"What we found is that an increase in the number of days that were hotter than 25 degrees centigrade decreased the population of birds, as well as the number of species, by about 2% or so," Khanna outlined.

Khanna pointed out specialist birds lost 7% to 16% of their populations because of climate change. She added other factors were already affecting birds, including pesticides, land use change and habitat loss. Researchers compared climate data for the same period alongside the studies.

The report found general species, like the North American sparrow, declined by almost 3% during the 25-year study. The threatened spotted owl and red-cockaded woodpecker, both specialist species, declined by 5%.

Khanna added they studied other variables that might influence birds' ability to adapt to climate change.

"Were there any changes that they might be doing in terms of their migratory routes or anything else because of this, that might reduce the negative impact of the changing climate? And we actually found no such effect," Khanna emphasized.

Khanna believes although birds are currently adapting to their respective environments, she is alarmed about the long-term effects on them if climate change continues. The Illinois Department of Natural Resources has recorded a total of 458 bird species in the state.
