Numbers
Within the EU, nearly 39% of bird species are in poor or bad conservation status, while 19% are officially classified as threatened, and 20% are in the “Near Threatened / declining” category.
Between 1990 and 2022, a monitoring index tracking 168 common bird species showed an overall 14% decline across the EU - demonstrating that even once-ubiquitous species are being swept into decline.
The Aquatic Warbler is declining by about 40% every 10 years, with fewer than 14,000 singing males left globally and breeding now limited to just ~40 sites.
