Bird decline: what the new eBird data reveal and how to act

Did you know that in North America, about 83 % of bird species lose more individuals in the areas where they were once the most abundant? This alarming trend was highlighted thanks to the analysis of 36 million observations collected via eBird, a citizen science platform dedicated to ornithology.

A concerning decline in areas of abundance

Recent studies have shown that bird populations decline the most in regions where they were historically most prevalent. This affects about 83 % of the species studied. The causes of this decline are multiple, including habitat loss, agricultural intensification, increasing urbanization, and climate change.

The crucial contribution of eBird data

eBird is a global platform where amateur and professional ornithologists submit their bird observations. With more than 36 million observations analyzed, scientists have been able to map population changes at an unprecedented scale. This data allows identifying the areas and species most affected, thereby providing valuable information to guide conservation efforts.

Tools to guide conservation

The integration of eBird data into conservation strategies proves particularly effective. For example, in the Great Lakes region of Canada, scientists have combined the data from eBird with other sources to improve the precision of demographic trends for 11 of the 18 marsh bird species studied. This integrated approach helps better understand patterns of abundance and distribution of species, thus facilitating the implementation of tailored conservation plans. (ebird.org)

How can you help protect birds?

As a nature enthusiast, you can actively contribute to the preservation of birds by:

• Participate in citizen science : Join programs like eBird to submit your observations. Each data point matters and helps scientists track population trends.

• Protect habitats : Support or get involved in local initiatives aimed at preserving and restoring birds' natural habitats.

• Raise awareness among your circle : Share your knowledge about the importance of birds and the threats they face.

• Adopt environmentally friendly practices : Reduce pesticide use, plant native species in your garden and avoid activities that disturb natural habitats.

Conclusion

Data from citizen science, such as those collected via eBird, play a crucial role in understanding and combatting the decline of bird populations in North America. As a nature lover, your engagement can make a difference. By participating in citizen science initiatives and adopting environmentally friendly behaviors, you contribute to the preservation of these precious species for our ecosystems.
