All birds respond differently to different extreme weather events; long- and short-distance migration bird species are impacted differently by climate change

The efforts of conservationists in protecting birds can now be more efficiently directed towards those species that are found to suffer more due to extreme weather events linked to climate change, showed a recent study.

All birds respond differently to different extreme weather events. The impact of different species is usually assessed by ecologists who observe a small number of them at different sites for a number of years, after which they form conclusions.

Researchers at the University of Wisconsin-Madison, United States, however, gave a shot at a significantly larger study to assess these impacts. They looked at 109 species across eastern North America for 15 years and used data from eBird, a global citizen-science initiative where bird enthusiasts submit checklists of bird sightings.

More than 830,000 such checklists — that included the types of species, their numbers, locations and times — were integrated with fine-scale satellite temperature and precipitation data from over a week, to a month or three months. This study — published in journal Global Change Biology August 21, 2020 — found several bird species could adapt to different extreme events, while a number of other species perished.
