Study estimates climate-driven heat extremes impacted tropical bird numbers by nearly 40 pc since 1950

NEW DELHI: Heat extremes driven by climate change may have reduced the world’s tropical bird population by 25-38 per cent on average since 1950, a study has estimated.

Findings published in the journal Nature Ecology and Evolution suggest that climate change is endangering tropical bird populations even in the absence of direct human pressures, such as changes in land use, researchers said.

The world’s tropical regions — having a high biodiversity — are home to nearly half of all bird species. However, many species are said to be living at temperatures close to their tolerance thresholds.
