No, it ain’t wind turbines.
Using data from the North American Breeding Bird Survey, the authors found that about half of the 261 species analyzed showed significant declines from 1987 to 2021, and a quarter showed accelerating declines. Hotspots of accelerating abundance decline were located in regions with high-intensity agriculture (high cropland area, fertilizer use, or pesticide use)
The first notable finding is that warm and warming regions coincide with areas of abundance decline (ΔN, Fig. 3, A and C, and figs. S7 and S8). This pattern is consistent with the evidence that bird populations are shifting their distributions northward as they track cooler conditions (31). Increases in temperatures have been shown to increase the risk of bird species’ extinction as a result of a lack of species adaptability to rapidly changing climatic conditions (32), and consistent temperature-related responses have been documented across both Europe and North America (33). Our results further support this by showing that areas experiencing greater warming (Fig. 3C) also exhibit stronger abundance declines, suggesting that rising temperatures may be a driver of recent bird population losses.
