Specialists argue that many species of birds are threatened by global warming. A study developed by the Audubon Society in 2014 has raised awareness regarding the effects of climate change on birds’ habitats. Global warming is known to have dramatic effects on the populations of birds in Canada and the United States. Scientists argued that out of the total number of 588 species of North American birds which were analyzed, about 314 are currently threatened by extinction.
If global warming continues to be fueled by greenhouse gas emissions, it will damage birds’ ecosystems even more. Based on the data found on Audubon website, researchers working there have use observations gathered from citizen-scientists on an extended timespan of about thirty years. These citizen-scientists collected their data during the annual Audubon Christmas Bird Count.
They have also used the North American Breeding Bird Survey which helped hem established the ‘climatic suitability’ for each and every species of birds. Climatic suitability encompasses the variations of precipitations and temperatures, but also the seasonal changes needed by every species to survive.
These scientists have also used scenarios including greenhouse gas emissions, mapping the ideal climate for every species of birds and also where it can be found in the future as the climate is continuously changing. The website of Audubon Society has a map showing every state in the country on which users may click to find out what species of birds are endangered or threatened by global warming in their areas.
For example, in Wisconsin, this list includes birds like the American kestrel, wild turkey, scarlet tanager, ruffed grouse, wood duck, bald eagle and many other species. If you click on a certain species appearing on the map, you can see predictions about the shifts between summer and winter in 2020, 2050 and 2080. It is possible that many very popular species may be affected by climate change in such a way that they may disappear in 30 to 60 years.
Another way to raise concern is imposed through the movie known as “The Messenger.” The documentary film underlines the challenges faced by so many songbirds on some locations in several parts of the world. Songbirds are known to be sensitive animals, being bound to perish first due to terrible conditions unfit for life.
